AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel
...
Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

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.

AMDGPU: Run SIFoldOperands after PeepholeOptimizer
...
PeepholeOptimizer cleans up redundant copies, which makes
the operand folding more effective.
