Pranav Bhandarkar 02d937d864 Hexagon - Add peephole optimizations for zero extends. 
* lib/Target/Hexagon/HexagonInstrInfo.td: Add patterns to combine a
	sequence of a pair of i32->i64 extensions followed by a "bitwise or"
	into COMBINE_rr.
	* lib/Target/Hexagon/HexagonPeephole.cpp: Copy propagate Rx in the
	instruction Rp = COMBINE_Ir_V4(0, Rx) to the uses of Rp:subreg_loreg.
	* test/CodeGen/Hexagon/union-1.ll: New test.
	* test/CodeGen/Hexagon/combine_ir.ll: Fix test.

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.
