OMPClauseWithPreInit now is the base for OMPClauseWithPostUpdate.

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
of signals while close will do something platform specific which results
in the FD potentially getting leaked.

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.

OpenMP 4.5 allows to privatize data members of current class in member

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.

pragma ms_struct has an effect on struct decls, and the effect is serialized
correctly already. But the "is ms_struct currently on" state wasn't before
this change.
This uses the same approach as `pragma clang optimize`: When writing a module,
the state isn't serialized, only when writing a pch file.

Turns "foo" into 'foo' (or vice versa, depending on configuration).
This makes it more convenient to follow the Google JavaScript style
guide:
https://google.github.io/styleguide/javascriptguide.xml?showone=Strings#Strings
This functionality is behind the option "JavaScriptQuotes", which can be:
* "leave" (no re-quoting)
* "single" (change to single quotes)
* "double" (change to double quotes)
This also changes single quoted JavaScript string literals to be treated
as tok::string_literal, not tok::char_literal, which fixes two unrelated
tests.
Patch by Martin Probst. Thank you.

This patch changes cc1 option for PGO profile use from
-fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>.
-fprofile-instr-use=<path> is now a driver only option.
In addition to decouple the cc1 option from the driver level option, this patch
also enables IR level profile use. cc1 option handling now reads the profile
header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM}
-- this is a common enum for -fprofile-instrument={}, for the profile
instrumentation), and invoke the pipeline to enable the respective PGO use pass.

This is like r262493, but for pragma detect_mismatch instead of pragma comment.
The two pragmas have similar behavior, so use the same approach for both.

`#pragma comment` was handled by Sema calling a function on ASTConsumer, and
CodeGen then implementing this function and writing things to its output.
Instead, introduce a PragmaCommentDecl AST node and hang one off the
TranslationUnitDecl for every `#pragma comment` line, and then use the regular
serialization machinery. (Since PragmaCommentDecl has codegen relevance, it's
eagerly deserialized.)
