[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
