+ Improved display names for allocators and deallocators
The checker checks if a deallocation function matches allocation one. ('free' for 'malloc', 'delete' for 'new' etc.)

gcc provides -mmfcrf and -mno-mfcrf for controlling what we call
the mfocrf target feature. Also, PPC is now making use of the
static function AddTargetFeature used by the Mips Driver code.

This reverts commit 5035c483b7fcbf0fa2a7afba24fa35a10995d195.
This schema change wasn't necessary after all. I'm going ith a different
solution that will hopefully use space more conservatively.

* Give the right diagnostic for 'restrict' applied to a non-pointer, non-reference type.
* Don't reject 'restrict' applied indirectly to an Objective-C object pointer type (eg, through template instantiation).

When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.
Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.
Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

These types will not have a CXXConstructExpr to do the initialization for
them. Previously we just used a simple call to ProgramState::bindLoc, but
that doesn't trigger proper checker callbacks (like pointer escape).

This option can be useful for end users who want to know why they
ended up with a ton of different variants of the "std" module in their
module cache. This problem should go away over time, as we reduce the
need for module variants, but it will never go away entirely.

Also update "test/Modules/macros.c" to test modified semantics:
-When there is an ambiguous macro, expand using the latest introduced version, not the first one.
-#undefs in submodules cause the macro to not be exported by that submodule, it doesn't cause
undefining of macros in the translation unit that imported that submodule.
This reduces macro namespace interference across modules.

uninstantiated exception specification when a special member within a class
template is both defaulted and given an exception specification on its first
declaration.

Previously all unimplemented methods for a class were grouped under
a single warning, with all the unimplemented methods mentioned
as notes. Based on feedback from users, most users would like
a separate warning for each method, with a note pointing back to
the original method declaration.

Register the nil tracking visitors with the region and refactor trackNullOrUndefValue a bit.
Also adds the cast and paren stripping before checking if the value is an OpaqueValueExpr
or ExprWithCleanups.

When Sema::RequireCompleteType() is given a class template
specialization type that then fails to instantiate, it returns
'true'. On subsequent invocations, it can return false. Make sure that
this difference doesn't change the result of
Sema::CompareReferenceRelationship, which is expected to remain stable
while we're checking an initialization sequence.

- Add head 'prfchwintrin.h' to define '_m_prefetchw' which is mapped to
LLVM/clang prefetch builtin
- Add option '-mprfchw' to enable PRFCHW feature and pre-define '__PRFCHW__'

Summary:
The only vector types a user can pass from MSVC code to clang code are
the ones from *mmintrin.h, so we only have to match the MSVC mangling
for these types. MSVC mangles the __m128 family of types as tag types,
which we match. For other vector types, we emit a unique tag type
mangling that won't match anything produced by MSVC.
