[Sema] Fix a crash-on-invalid when a template parameter list has a class
definition or non-reference class type.
The crash occurs when there is a template parameter list in a class that
is missing the closing angle bracket followed by a definition of a
struct. For example:
class C0 {
public:
template<typename T, typename T1 = T // missing closing angle bracket
struct S0 {};
C0() : m(new S0<int>) {}
S0<int> *m;
};
This happens because the parsed struct is added to the scope of the
enclosing class without having its access specifier set, which results
in an assertion failure in SemaAccess.cpp later.
This commit fixes the crash by adding the parsed struct to the enclosing
file scope and marking structs as invalid if they are defined in
template parameter lists.

With this patch, the diagnostic would point to either Line 3, Column 5

This is done by emitting source location metadata for each return

the appropriate metadata so that it can prepare and deduplicate reports.

Emit warning when throw exception in destruct or dealloc functions which has a
(possible implicit) noexcept specifier
Throwing in the destructor is not good (C++11 change try to not allow see below).
But in reality, those codes are exist.
C++11 [class.dtor]p3:
A declaration of a destructor that does not have an exception-specification is
implicitly considered to have the same exception specification as an implicit
declaration.
With this change, the application worked before may now run into runtime
termination. My goal here is to emit a warning to provide only possible info to
where the code may need to be changed.
First there is no way, in compile time to identify the “throw” really throw out
of the function. Things like the call which throw out… To keep this simple,
when “throw” is seen, checking its enclosing function(only destructor and
dealloc functions) with noexcept(true) specifier emit warning.
Here is implementation detail:
A new member function CheckCXXThrowInNonThrowingFunc is added for class Sema
in Sema.h. It is used in the call to both BuildCXXThrow and
TransformCXXThrowExpr.
The function basic check if the enclosing function with non-throwing noexcept
specifer, if so emit warning for it.
The example of warning message like:
k1.cpp:18:3: warning: ''~dependent_warn'' has a (possible implicit) non-throwing
noexcept specifier. Throwing exception may cause termination.
[-Wthrow-in-dtor]
throw 1;

This intends to make the compression of the debug information
controllable from the driver. The following is the behaviour:
-gz enable compression (ambiguous for format, will default to zlib-gnu)
-gz=none disable compression
-gz=zlib-gnu enable compression (deprecated GNU style zlib compression)
-gz=zlib enable compression (zlib based compression)
Although -Wa,-compress-debug-sections works, it should be discouraged
when using the driver to invoke the assembler. However, we permit the
assembler to accept the GNU as style argument --compress-debug-sections
to maintain compatibility.
Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally
specific -g for debug information to be generated.

PR33552: Distinguish between declarations that are owned by no module and
declarations that are owned but unconditionally visible.
This allows us to set declarations as visible even if they have a local owning
module, without losing information. In turn, that means that our Objective-C
support can keep on incorrectly assuming the "hidden" bit on the declaration is
the whole story with regard to name visibility. This will also be useful once
we support the C++ Modules TS export semantics.
Objective-C name visibility is still incorrect in any case where the "hidden"
bit is not the complete story: for instance, in Objective-C++ the set of
visible categories will be wrong during template instantiation, and with local
submodule visibility enabled it will be wrong when building modules. Fixing that
will require a major overhaul of how visibility is handled for Objective-C (and
particularly for categories).

SwiftCC: Perform physical layout when computing coercion types
We need to take type alignment padding into account whe computing physical
layouts.
The layout must be compatible with the input layout, offsets are defined in
terms of offsets within a packed struct which are computed in terms of the alloc
size of a type.
Usingthe store size we would insert padding for the following type for example:
struct {
int3 v;
long long l;
} __attribute((packed))
On x86-64 int3 is padded to int4 alignment. The swiftcc type would be
<{ <3 x float>, [4 x i8], i64 }> which is not compatible with <{ <3 x float>,
i64 }>.
The latter has i64 at offset 16 and the former at offset 20.

Correct VectorCall x86 (32 bit) behavior for SSE Register Assignment
In running some internal vectorcall tests in 32 bit mode, we discovered that the
behavior I'd previously implemented for x64 (and applied to x32) regarding the
assignment of SSE registers was incorrect. See spec here:
https://msdn.microsoft.com/en-us/library/dn375768.aspx
My previous implementation applied register argument position from the x64
version to both. This isn't correct for x86, so this removes and refactors that
section. Additionally, it corrects the integer/int-pointer assignments. Unlike
x64, x86 permits integers to be assigned independent of position.
Finally, the code for 32 bit was cleaned up a little to clarify the intent,
as well as given a descriptive comment.

Function with unparsed body is a definition
While a function body is being parsed, the function declaration is not considered
as a definition because it does not have a body yet. In some cases it leads to
incorrect interpretation, the case is presented in
https://bugs.llvm.org/show_bug.cgi?id=14785:
```
template<typename T> struct Somewhat {
void internal() const {}
friend void operator+(int const &, Somewhat<T> const &) {}
};
void operator+(int const &, Somewhat<char> const &x) { x.internal(); }
```
When statement `x.internal()` in the body of global `operator+` is parsed, the type
of `x` must be completed, so the instantiation of `Somewhat<char>` is started. It
instantiates the declaration of `operator+` defined inline, and makes a check for
redefinition. The check does not detect another definition because the declaration
of `operator+` is still not defining as does not have a body yet.
To solves this problem the function `isThisDeclarationADefinition` considers
a function declaration as a definition if it has flag `WillHaveBody` set.

Disable generation of counting-function attribute if no_instrument_function
attribute is present in function.
Interaction between -pg and no_instrument_function is the desired behavior

This is required for fixing a crash in Linux kernel when function tracing
is enabled.

CodeGen: Cast temporary variable to proper address space
In C++ all variables are in default address space. Previously change has been
made to cast automatic variables to default address space. However that is
not sufficient since all temporary variables need to be casted to default
address space.
This patch casts all temporary variables to default address space except those
for passing indirect arguments since they are only used for load/store.
This patch only affects target having non-zero alloca address space.

clang-format: Fix C99 designated initializers corner cases
Summary:
This fixes the missing space before the designated initializer when `Cpp11BracedListStyle=false` :
const struct A a = { .a = 1, .b = 2 };
^
Also, wrapping between opening brace and designated array initializers used to have an excessive penalty (like breaking between an expression and the subscript operator), leading to unexpected wrapping:
const struct
Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa =
{[1] =
aaaaaaaaaaaaaaaaaaaaaaaaaaa,
[2] =
bbbbbbbbbbbbbbbbbbbbbbbbbbb};
instead of:
const struct
Aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa = {
[1] =
aaaaaaaaaaaaaaaaaaaaaaaaaaa,
[2] =
bbbbbbbbbbbbbbbbbbbbbbbbbbb};
Finally, designated array initializers are not binpacked, just like designated member initializers.

Call setMustBuildLookupTable on TagDecls in ExternalASTMerger
Summary:
setMustBuildLookupTable should be called on imported TagDecls otherwise we may fail
to import their member decls (if they have any).
Not calling the setMustBuildLookupTable method results in a failure in the attached test
case when lookup for the 'x' member fails on struct S, which hasn't had its decls imported
elsewhere. (By contrast the member-in-struct testcase hasn't run into this issue
because the import of its decls is triggered when the struct instance is defined, and the
member access follows this).
