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: Generalize matching of v_med3_f32
...
I think this is safe as long as no inputs are known to ever
be nans.
Also add an intrinsic for fmed3 to be able to handle all safe
math cases.

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