Now that pragma comment and pragma detect_mismatch are implemented, this might
just work.
Some pragmas aren't serialized yet (from the top of my head: code_seg, bss_seg,
data_seg, const_seg, init_seg, section, vtordisp), but these are as far as I
know usually pushed and popped within the header and usually don't leak out.
If it turns out the current PCH support isn't good enough yet, we can turn it
off again.

Summary:
Using -no-integrated-as causes -mcpu=krait to be transformed into
-march=armv7-a today. This precludes the assembler from using
instructions like sdiv, which are present for krait. Cortex-a15 is the
closest subset of functionality for krait, so we should switch the
assembler to use that instead.

This patch provide basic implementation of codegen for teams directive, excluding all clauses except dist_schedule. It also fixes parts of AST reader/writer to enable correct pre-compiled header handling.

Use it to calculate UserLabelPrefix, instead of specifying it (often
incorrectly).
Note that the *actual* user label prefix has always come from the
DataLayout, and is handled within LLVM. The main thing clang's
TargetInfo::UserLabelPrefix did was to set the #define value. Having
these be different from each-other is just silly.

In dealloc methods, the analyzer now warns when -dealloc is called directly on
a synthesized retain/copy ivar instead of -release. This is intended to find mistakes of
the form:
- (void)dealloc {
[_ivar dealloc]; // Mistaken call to -dealloc instead of -release
[super dealloc];
}

Summary:
While diagnosing a CXXNewExpr warning, we were calling isInSystemHeader(), which expect to be
called with a valid source location. This causes an assertion failure if the location is unknown.
A quick grep shows it's not without precedent to guard calls to the function with a
"Loc.isValid()".
This fixes a test failure in LLDB, which always creates object with invalid source locations as it
does not (always) have access to the source.

While pushing switch statements onto the region stack we neglected to
specify their start/end locations. This results in a crash (PR26825) if
we end up in nested macro expansions without enough information to
handle the relevant file exits.
I added a test in switchmacro.c and fixed up a bunch of incorrect CHECK
lines that specify strange end locations for switches.

For compatibility with GCC, classify __m64 as SSE.
However, clang is a platform compiler for certain targets; retain our
old behavior on those targets: classify __m64 as integer.
This fixes PR26832.

The SafelyCloseFileDescriptor machinery does the right thing in the face

Summary:
This patch implements the launching of a target region in the presence of a nested teams region, i.e calls tgt_target_teams with the required arguments gathered from the enclosed teams directive.
The actual codegen of the region enclosed by the teams construct will be contributed in a separate patch.

Applying the following restrictions for block types in OpenCL (v2.0 s6.12.5):
- __block storage class is disallowed
- every block declaration must be const qualified and initialized
- a block can't be used as a return type of a function
- a blocks can't be used to declare a structure or union field
- extern speficier is disallowed
Corrected image and sampler types diagnostics with struct and unions.

This is a sad workaround for the lack of plugin support in libclang. Depends
on D17807, a tools-extra change that also contains the test case.
This is designed to be easy to remove again if libclang ever grows proper
plugin support.

Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct.
User-defined reductions are defined as
#pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )]
These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The
combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will
denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting
combined value after executing the combiner.
As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause
will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier
omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

I should have checked and imported D's in-class initializer.
Instead I accidentally used ToField's in-class initializer,
which is always NULL so ToField will never get one.

Previously, the ASTImporter, when copying a FieldDecl, would make the
new FieldDecl use the exact same in-class initializer as the original
FieldDecl, which is a problem since the initializer is in the wrong AST.
The initializer must be imported, just like all the other parts of the
field.
Doug Gregor reviewed this fix.
