Enabling 3DNow! prefetch instruction support for a few AMD processors in the
clang front end. This change will allow the __PRFCHW__ macro to be set on these
processors and hence include prfchwintrin.h in x86intrin.h header. Support for
the intrinsic itself seems to have already been added in r178041.

Add implementations of the MSVC barrier intrinsics

Summary:
These are deprecated in VS 2012 according to MSDN.  They don't actually
compile down to any code.  They prevent the compiler from reordering
memory accesses across the barrier, which is what a memory-clobbering
volatile asm does.

Add support to the Clang driver for forwarding all of gfortran's flags
to GCC when asked to compile a fortran input.

This fixes a regression with essentially every Fortran compile since we
started rejecting unknown flags. Also moves a mis-classified gfortran
flag into the nicely documented set.
