Lei Huang c0f9188920 [PowerPC] Add codegen for VSX word extract convert to FP 
Add codegen for VSX word extract conversion from signed/unsigned to single/double
precision.

For UINT_TO_FP:
Extract word unsigned and convert to float was implemented in https://reviews.llvm.org/D20239.
Here we will add the missing extract integer and conversion to double. This
utilizes the new P9 instruction xxextractuw to extracting an integer element
when the result will be converted to double thereby saving 2 direct moves
(VSR <-> GPR).

For SINT_TO_FP:
We will implement the following sequence which will also reduce the number of
instructions by saving 2 direct moves.

v4i32->f32:
        xxspltw
        xvcvsxwsp
        xscvspdpn

v4i32->f64:
        xxspltw
        xvcvsxwdp

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

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.
