Enhance OpenMP parser tests from r197553 / r197598
Move some of the verifier directives away from the end of the pragma line.
This ensures that the diagnostics relate to the trailing token being tested and
not the verifier comments which are themselves part of the token stream.

clang-format-diff.py: fix -regex/-iregex matching
While debating the finer points of file extension matching, we somehow missed
the bigger problem that the current code will match anything starting with the
default or user-specified pattern (e.g. lit.site.cfg.in).
Fix this by doing what find(1) does, implicitly wrapping the pattern with ^$.
Objective-C. After providing a fix-it for a
cstring, converted to NSString, produce the
matching AST for it. This also required some
refactoring of the previous code. // rdar://14106083

Remove OpenCL-specific type keywords and specifiers
This commit kills off custom type specifier and keyword handling of OpenCL C
data types.
Although the OpenCL spec describes them as keywords, we can handle them more
elegantly as predefined types. This should provide better error correction and
code completion as well as simplifying the implementation.
The primary intention is however to simplify the C/C++ parser and save some
packed bits on AST structures that had been extended in r170432 just for
OpenCL.

Add a 's' specifications to AArch64.
This has no functionality change as clang adds explicit alignment info for

[ms-cxxabi] The 'most derived' ctor parameter usually comes last
Unlike Itanium's VTTs, the 'most derived' boolean or bitfield is the
last parameter for non-variadic constructors, rather than the second.
For variadic constructors, the 'most derived' parameter comes after the
'this' parameter. This affects constructor calls and constructor decls
in a variety of places.

First we would check on ~S() and error about the ambigous delete functions,
and then we would error about using the deleted destructor.
If the destructor is deleted, there's no need to check it.
Also, move the check from Sema::ActOnFields to CheckCompleteCXXClass. These
are run at almost the same time, called from ActOnFinishCXXMemberSpecification.
However, CHeckCompleteCXXClass may mark a defaulted destructor as deleted, and
if that's the case we don't want to check it.

Refactor and micro-optimize ConsumeToken()
1) Introduce TryConsumeToken() to handle the common test-and-consume pattern.
This brings about readability improvements in the parser and optimizes to avoid
redundant checks in the common case.
2) Eliminate the ConsumeCodeCompletionTok special case from ConsumeToken(). This
was used by only one caller which has been switched over to the more
appropriate ConsumeCodeCompletionToken() function.

Simplify RevertibleTypeTraits as a form of contextual keyword
Now that we emit diagnostics for keyword-as-identifier hacks (-Wkeyword-compat)
we can go ahead and simplify some of the old revertible keyword support.
This commit adds a TryIdentKeywordUpgrade() function to mirror the recently
added TryKeywordIdentFallback() and uses it to replace the hard-coded list of

Modules: Don't warn upon missing headers while reading the module map.
Instead, mark the module as unavailable so that clang errors as soon as

This works towards the long-term goal of not stat'ing the header files at all

being built (there is a corresponding FIXME in parseHeaderDecl()). However, it

__builtin_va_list and friends have been showing up where they shouldn't for way
to long, making unwanted appearences in -ast-print, tooling and source level

This commit factors down the implicit typedef and record creation facilities to
ensure they're marked implicit.
Also fixes a unit test that was testing incorrect behaviour, and removes old
hacks in the DeclPrinter that tried to skip implicit declarations manually.
