Matt Arsenault 3a9a1ac61b AMDGPU: Use unsigned compare for eq/ne 
For some reason there are both of these available, except
for scalar 64-bit compares which only has u64. I'm not sure
why there are both (I'm guessing it's for the one bit inputs we
don't use), but for consistency always using the
unsigned one.
