Implement C++ DR727, which permits explicit specializations at class scope.
More generally, this permits a template to be specialized in any scope in which
it could be defined, so this also supersedes DR44 and DR374 (the latter of
which we previously only implemented in C++11 mode onwards due to unclarity as
to whether it was a DR).

[Parser] (C++) Make -Wextra-semi slightly more useful
Summary:
Let's suppose the `-Weverything` is passed.
Given code like
```
void F() {}
;
```
If the code is compiled with `-std=c++03`, it would diagnose that extra sema:
```
<source>:2:1: warning: extra ';' outside of a function is a C++11 extension [-Wc++11-extra-semi]
;
^~
```
If the code is compiled with `-std=c++11`, it also would diagnose that extra sema:
```
<source>:2:1: warning: extra ';' outside of a function is incompatible with C++98 [-Wc++98-compat-pedantic]
;
^~
```
But, let's suppose the C++11 or higher is used, and the used does not care
about `-Wc++98-compat-pedantic`, so he disables that diagnostic.
And that silences the complaint about extra `;` too.
And there is no way to re-enable that particular diagnostic, passing `-Wextra-semi` does nothing...
Now, there is also a related `no newline at end of file` diagnostic, which is also emitted by `-Wc++98-compat-pedantic`
```
<source>:2:2: warning: C++98 requires newline at end of file [-Wc++98-compat-pedantic]
;
^
```
But unlike the previous case, if `-Wno-c++98-compat-pedantic` is passed, that diagnostic stays displayed:
```
<source>:2:2: warning: no newline at end of file [-Wnewline-eof]
;
^
```
This diff refactors the code so `-Wc++98-compat-extra-semi` can be re-enabled, after the `-Wc++98-compat-pedantic` was disabled.
This seems ugly, but there does not seem to be any saner way.

[CFG] [analyzer] Add construction context to C++ return-by-value call elements.
This patch adds a new CFGStmt sub-class, CFGCXXRecordTypedCall, which replaces
the regular CFGStmt for the respective CallExpr whenever the CFG has additional
information to provide regarding the lifetime of the returned value.
This additional call site information is represented by a ConstructionContext
(which was previously used for CFGConstructor elements) that provides references
to CXXBindTemporaryExpr and MaterializeTemporaryExpr that surround the call.
This corresponds to the common C++ calling convention solution of providing
the target address for constructing the return value as an auxiliary implicit
argument during function call.
One of the use cases for such extra context at the call site would be to perform
any sort of inter-procedural analysis over the CFG that involves functions
returning objects by value. In this case the elidable constructor at the return
site would construct the object explained by the context at the call site, and
its lifetime would also be managed by the caller, not the callee.
The extra context would also be useful for properly handling the return-value
temporary at the call site, even if the callee is not being analyzed
inter-procedurally.

[clang-format] Improve detection of Objective-C block types
Summary:
Previously, clang-format would detect the following as an
Objective-C block type:
FOO(^);
when it actually must be a C or C++ macro dealing with an XOR
statement or an XOR operator overload.
According to the Clang Block Language Spec:
https://clang.llvm.org/docs/BlockLanguageSpec.html
block types are of the form:
int (^)(char, float)
and block variables of block type are of the form:
void (^blockReturningVoidWithVoidArgument)(void);
int (^blockReturningIntWithIntAndCharArguments)(int, char);
void (^arrayOfTenBlocksReturningVoidWithIntArgument[10])(int);
This tightens up the detection so we don't unnecessarily detect
C macros which pass in the XOR operator.

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

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

[clang-format] Use NestedBlockIndent as a 0 column in formatted raw strings
Summary:
This makes the formatter of raw string literals use NestedBlockIndent for
determining the 0 column of the content inside. This makes the formatting use
less horizonal space and fixes a case where two newlines before and after the
raw string prefix were selected instead of a single newline after it:
Before:
```
aaaa = ffff(
R"pb(
key: value)pb");
```
After:
```
aaaa = ffff(R"pb(
key: value)pb");
```

[CodeGen] Emit lifetime.ends in both EH and non-EH blocks
Before this, we'd only emit lifetime.ends for these temps in
non-exceptional paths. This potentially made our stack larger than it
needed to be for any code that follows an EH cleanup. e.g. in
```
struct Foo { char cs[32]; };
void escape(void *);
struct Bar { ~Bar() { char cs[64]; escape(cs); } };
Foo getFoo();
void baz() {
Bar b;
getFoo();
}
```
baz() would require 96 bytes of stack, since the temporary from getFoo()
only had a lifetime.end on the non-exceptional path.
This also makes us keep hold of the Value* returned by
EmitLifetimeStart, so we don't have to remake it later.

[analyzer] Correctly model iteration through "nil" objects
Previously, iteration through nil objects which resulted from
objc-messages being set to nil were modeled incorrectly.
There are a couple of notes about this patch:
In principle, ExprEngineObjC might be left untouched IFF osx.loops
checker is enabled.
I however think that we should not do something
completely incorrect depending on what checkers are left on.
We should evaluate and potentially remove altogether the isConsumedExpr
performance heuristic, as it seems very fragile.

When substituting previously-checked template arguments into a template
template parameter that is an expanded parameter pack, only substitute into the
current slice, not the entire pack.
This reduces the checking of N template template arguments for an expanded
parameter pack containing N parameters from quadratic time to linear time in
the length of the pack. This is important because one (and possibly the only?)
general technique for splitting a template parameter pack in linear time
depends on doing this.

[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.

Summary:
This provides no measurable build speedup, but it reinstates an
optimization from r112038 that was lost in r179618. It requires moving
CapturedScopeInfo::Capture out to clang::sema, which might be too

other AST nodes.
