Bill Schmidt fc4d5c63d4 Use direct types in most PowerPC Altivec instructions and patterns. 
This follows up Ulrich Weigand's work in PPCInstrInfo.td and
PPCInstr64Bit.td by doing the corresponding work for most of the
Altivec patterns.  I have not been able to do anything for the
following classes of instructions:

(1) Vector logicals.  These don't have corresponding intrinsics and
don't have a single obvious vector type.  So far as I can tell I need
to leave these as VRRC.  Affected instructions are:  VAND, VANDC,
VNOR, VOR, VXOR, V_SET0.

(2) Instructions that make use of vector shuffle.  The selection code
promotes all shuffles to v16i8, so any pattern that matches on a
shuffle is constrained.  I haven't found any way to make the patterns
match on their natural types, so I plan to leave these as VRRC.
Affected instructions are:  VMRG*, VSPLTB, VSPLTH, VSPLTW, VPKUHUM,
VPKUWUM.

No change in behavior is anticipated.

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
