Zhan Jun Liau 0606cb413f [SystemZ] Avoid generating 2 XOR instructions for (and (xor x, -1), y) 
Summary:
Created a pattern to match 64-bit mode (and (xor x, -1), y)
to a shorter sequence of instructions.

Before the change, the canonical form is translated to:
        xihf    %r3, 4294967295
        xilf    %r3, 4294967295
        ngr     %r2, %r3

After the change, the canonical form is translated to:
        ngr     %r3, %r2
        xgr     %r2, %r3

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
