[CodeGen] Try to not call a dtor after lifetime.end
If CodeGenFunction::EmitCall is:
- asked to emit a call with an indirectly returned value,
- given an invalid return value slot, and
- told the return value of the function it's calling is unused
then it'll make its own temporary, and add lifetime markers so that the
temporary's lifetime ends immediately after the call.
The early lifetime.end becomes problematic when we need to run a
destructor on the result of the function.
Instead of unconditionally saying that results of all calls are used
here (which would be correct, but would also cause us to never emit
lifetime markers for these temporaries), we just build our own temporary
to pass in when a dtor has to be run.

[Sema] Make getCurFunction() return null outside function parsing
Summary:
Before this patch, Sema pre-allocated a FunctionScopeInfo and kept it in
the first, always present element of the FunctionScopes stack. This
meant that Sema::getCurFunction would return a pointer to this
pre-allocated object when parsing code outside a function body. This is
pretty much always a bug, so this patch moves the pre-allocated object
into a separate unique_ptr. This should make bugs like PR36536 a lot
more obvious.
As you can see from this patch, there were a number of places that
unconditionally assumed they were always called inside a function.
However, there are also many places that null checked the result of
getCurFunction(), so I think this is a reasonable direction.

CodeGen: Fix address space of indirect function argument
The indirect function argument is in alloca address space in LLVM IR. However,
during Clang codegen for C++, the address space of indirect function argument
should match its address space in the source code, i.e., default addr space, even
for indirect argument. This is because destructor of the indirect argument may
be called in the caller function, and address of the indirect argument may be
taken, in either case the indirect function argument is expected to be in default
addr space, not the alloca address space.
Therefore, the indirect function argument should be mapped to the temp var
casted to default address space. The caller will cast it to alloca addr space
when passing it to the callee. In the callee, the argument is also casted to the
default address space and used.
CallArg is refactored to facilitate this fix.

Push a function scope when parsing function bodies without a declaration
Summary:
This is PR36536.
There are a few ways to reach Sema::ActOnStartOfFunctionDef with a null
Decl. Currently, the parser continues on to attempt to parse the
statements in the function body without pushing a function scope or
declaration context. However, lots of statement parsing logic relies on
getCurFunction() returning something reasonable. It turns out that
getCurFunction() will never return null today because of an optimization
where Sema pre-allocates one FunctionScopeInfo and reuses it when
possible. This goes wrong when something inside the function body causes
us to push another function scope, such as requiring an implicit
definition of a special member function. Reusing the state clears it
out, which will lead to bugs. In PR36536, we found that the SwitchStack
gets unbalanced, because we push a switch, clear out the stack, and then
try to pop a switch that isn't there.
As a follow-up, I plan to move the pre-allocated FunctionScopeInfo out
of the FunctionScopes stack. This means the FunctionScopes stack will
often be empty, and callers of getCurFunction() will need to check for
null.

[FrontEnd] Allow overriding the default C/C++ -std via CMake vars
Provide two new CMake cache variables -- CLANG_DEFAULT_STD_C
and CLANG_DEFAULT_STD_CXX -- that can be used to override the default
C/ObjC and C++/ObjC++ standards appropriately. They can be set to one of
the identifiers from LangStandards.def, or left unset (the default) to
respect the current platform default.
This option is mostly intended for compiler vendors that may wish
to adjust the defaults their compilers are using. For example, Gentoo
planned to use it to set clang and gcc to matching standards, so that
we could maintain as much compatibility between different compilers
as possible.
The code relies on explicit identifiers rather than the string aliases
for simplicity. This saves us from the necessity of parsing aliases at
build-time or adding additional processing at runtime. For the latter
case, it also adds trivial value check -- if incorrect value is passed,
the code simply fails to compile through referencing an undefined
constant.
If the variable is used to redefine the default standard, the explicit
value overrides the special case for PS4. It is done this way mostly
following other kinds of variables where 'platform defaults' are
redefined.

[Analyzer] More accurate modeling about the increment operator of the operand with type bool.
Summary:
There is a problem with analyzer that a wrong value is given when modeling the increment operator of the operand with type bool. After `rL307604` is applied, a unsigned overflow may occur.
Example:
```
void func() {
bool b = true;
// unsigned overflow occur, 2 -> 0 U1b
b++;
}
```
The use of an operand of type bool with the ++ operators is deprecated but valid untill C++17. And if the operand of the increment operator is of type bool, it is set to true.
This patch includes two parts:
- If the operand of the increment operator is of type bool or type _Bool, set to true.
- Modify `BasicValueFactory::getTruthValue()`, use `getIntWidth()` instead `getTypeSize()` and use `unsigned` instead `signed`.

[analyzer] Improves the logic of GenericTaintChecker identifying stdin.
Summary:
GenericTaintChecker can't recognize stdin in some cases. The reason is that `if (PtrTy->getPointeeType() == C.getASTContext().getFILEType()` does not hold when stdin is encountered.
My platform is ubuntu16.04 64bit, gcc 5.4.0, glibc 2.23. The definition of stdin is as follows:
```
__BEGIN_NAMESPACE_STD
/* The opaque type of streams. This is the definition used elsewhere. */
typedef struct _IO_FILE FILE;
___END_NAMESPACE_STD
...
/* The opaque type of streams. This is the definition used elsewhere. */
typedef struct _IO_FILE __FILE;
...
/* Standard streams. */
extern struct _IO_FILE *stdin; /* Standard input stream. */
extern struct _IO_FILE *stdout; /* Standard output stream. */
extern struct _IO_FILE *stderr; /* Standard error output stream. */
```
The type of stdin is as follows AST:
```
ElaboratedType 0xc911170'struct _IO_FILE'sugar
`-RecordType 0xc911150'struct _IO_FILE'
`-CXXRecord 0xc923ff0'_IO_FILE'
```
`C.getASTContext().GetFILEType()` is as follows AST:
```
TypedefType 0xc932710 'FILE' sugar
|-Typedef 0xc9111c0 'FILE'
`-ElaboratedType 0xc911170 'struct _IO_FILE' sugar
`-RecordType 0xc911150 'struct _IO_FILE'
`-CXXRecord 0xc923ff0 '_IO_FILE'
```
So I think it's better to use `getCanonicalType()`.

Remove -i command line option, add -imultilib
I discovered that '-i' is a command line option for the driver,
however it actually does not do anything and is not supported by any
other compiler. In fact, it is completely undocumented for Clang.
I found a couple of instances of people confusing it with one of
the variety of other command line options that control the driver.
Because of this, we should delete this option so that it is clear
that it isn't valid.
HOWEVER, I found that GCC DOES support -imultilib, which the -i
was hiding our lack of support for. We currently only use imultilib
for the purpose of forwarding to gfortran (in a specific test written
by chandlerc for this purpose).
imultilib is a rarely used (if ever?) feature that I could find no
references to on the internet, and in fact, my company's massive test
suite has zero references to it ever being used.
SO, this patch removes the -i option so that we will now give an error
on its usage (so that it won't be confused with -I), and replaces it with
-imultilib, which is now specified as a gfortran_group option.

Fix the hasType() AST matcher to not assert when the QualType is invalid.
There's not a particularly good way to test this with the AST matchers unit tests because the only way to get an invalid type (that I can devise) involves creating parse errors, which the test harness always treats as a failure. Instead, a clang-tidy test case will be added in a follow-up commit based on the original bug report.

[Attr] Fix parameter indexing for several attributes
The patch fixes a number of bugs related to parameter indexing in
attributes:
* Parameter indices in some attributes (argument_with_type_tag,
pointer_with_type_tag, nonnull, ownership_takes, ownership_holds,
and ownership_returns) are specified in source as one-origin
including any C++ implicit this parameter, were stored as
zero-origin excluding any this parameter, and were erroneously
printing (-ast-print) and confusingly dumping (-ast-dump) as the
stored values.
* For alloc_size, the C++ implicit this parameter was not subtracted
correctly in Sema, leading to assert failures or to silent failures
of __builtin_object_size to compute a value.
* For argument_with_type_tag, pointer_with_type_tag, and
ownership_returns, the C++ implicit this parameter was not added
back to parameter indices in some diagnostics.
This patch fixes the above bugs and aims to prevent similar bugs in
the future by introducing careful mechanisms for handling parameter
indices in attributes. ParamIdx stores a parameter index and is
designed to hide the stored encoding while providing accessors that
require each use (such as printing) to make explicit the encoding that
is needed. Attribute declarations declare parameter index arguments
as [Variadic]ParamIdxArgument, which are exposed as ParamIdx[*]. This
patch rewrites all attribute arguments that are processed by
checkFunctionOrMethodParameterIndex in SemaDeclAttr.cpp to be declared
as [Variadic]ParamIdxArgument. The only exception is xray_log_args's
argument, which is encoded as a count not an index.
