The current VSX feature for PowerPC specifies availability of the VSX
instructions added with the 2.06 architecture version.  With 2.07, the
architecture adds new instructions to both the Category:Vector and
Category:VSX instruction sets.  Additionally, unaligned vector storage
operations have improved performance.

This patch adds a feature to provide access to the new instructions
and performance capabilities of Power8.  For compatibility with GCC,
the feature is controlled via a new -mpower8-vector switch, and the
feature causes the __POWER8_VECTOR__ builtin define to be generated by
the preprocessor.

There is a companion patch for llvm being committed at the same time.

Make it possible to pass NULL through variadic functions on 64-bit
Windows targets. The Visual C++ headers define NULL to 0, when they
should define it to 0LL on Win64 so that NULL is a pointer-sized
integer.

Summary:
There was an assumption that there were no matchers that were overloaded
on matchers and other types of arguments.
This assumption was broken recently with the addition of new matcher
overloads.

Summary:
Remove unnecessary wrapping for the 0 and 1 matcher cases of
makeAllOfComposite(). We don't need a variadic wrapper for those cases.
Refactor TrueMatcher to take advandage of the new conversions between
DynTypedMatcher and Matcher<T>. Also, make it a singleton.
This change improves our clang-tidy related benchmarks by ~12%.

Summary:
This change adds an experimental flag -fsanitize-address-field-padding=N (0, 1, 2)
to clang and driver. With this flag ASAN will be able to detect some cases of
intra-object-overflow bugs,
see https://code.google.com/p/address-sanitizer/wiki/IntraObjectOverflow

There is no actual functionality here yet, just the flag parsing.
The functionality is being reviewed at http://reviews.llvm.org/D5687

Test Plan: Build and run SPEC, LLVM Bootstrap, Chrome with this flag.

This patch generates some helper variables that used as private copies of the corresponding original variables inside an OpenMP 'parallel' directive. These generated variables are initialized by copy using values of the original variables (with the copy constructor, if any). For arrays, initializator is generated for single element and in the codegen procedure this initial value is automatically propagated between all elements of the private copy.
In outlined function, references to original variables are replaced by the references to these private helper variables. At the end of the initialization of the private variables an implicit barier is generated by calling __kmpc_barrier(...) runtime function to be sure that all threads were initialized using original values of the variables.
