Bill Schmidt 055d207426 [PowerPC] More fast-isel chunks (returns and integer extends) 
Incremental improvement to fast-isel for PPC64.  This allows us to
select on ret, sext, and zext.  Filling in sext/zext improves some of
the existing logic in handling compare-immediates that needed extends.

A simplified return convention for fast-isel is also added to the
PPC64 calling conventions.  All call/return processing for DAG
selection is handled with custom code, so there isn't an existing CC
to rely on here.  The include of PPCGenCallingConv.inc causes compiler
warnings due to the 32-bit calling conventions that are not used, so
the dummy function "usePPC32CCs()" is added here to silence those.

Test cases for the return and extend logic are added.

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.
