feature; support these options as well.

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.

- 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__'

Driver will now error when trying to compile for V2 or V3.
Removal of V2 and V3 support will allow us to simplify the hexagon
back-end.

'R' An address that can be sued in a non-macro load or store.
Including missing positive test case and fixed typo for r176453.
Thanks to Richard Smith for catching this!

'long' and 'long long' are different for the purposes of mangling.

This allows Clang to detect and deal wih __atomic_* operations properly on
AArch64. Previously we produced an error when encountering them at high
optimisation levels.

Introduces these negation forms explicitly and uses them to control a new
"altivec" target feature for PowerPC. This allows avoiding generating
Altivec instructions on processors that support Altivec.
The new test case verifies that the Altivec "lvx" instruction is not
used when -fno-altivec is present on the command line.

In cooperation with the LLVM patch, this should implement all scalar front-end
parts of the C and C++ ABIs for AArch64.
This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.
Further reviews would be gratefully received.

Linux too, as I think we inherited it from there. The ABI spec says 128-bit,
although I think SGI's compiler on IRIX may be the only thing ever to support
this.

the output size is greater than the register size. No truncation occurs with
those. Reword warning to make it clearer what's the problem is.
