Zi Xuan Wu 287883a58b [PowerPC] Enhance the fast selection of cmp instruction and clean up related asserts 
Fast selection of llvm icmp and fcmp instructions is not handled well about VSX instruction support.

We'd use VSX float comparison instruction instead of non-vsx float comparison instruction 
if the operand register class is VSSRC or VSFRC because i32 and i64 are mapped to VSSRC and 
VSFRC correspondingly if VSX feature is opened.

If the target does not have corresponding VSX instruction comparison for some type, 
just copy VSX-related register to common float register class and use non-vsx comparison instruction.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
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 are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
