Marek Olsak 2477ef0a7f AMDGPU: Add a fast path for icmp.i1(src, false, NE) 
Summary:
This allows moving the condition from the intrinsic to the standard ICmp
opcode, so that LLVM can do simplifications on it. The icmp.i1 intrinsic
is an identity for retrieving the SGPR mask.

And we can also get the mask from and i1, or i1, xor i1.
