AMDGPU: Allow SIShrinkInstructions to work in non-SSA
...
Immediates can be folded as long as the immediate is a vreg.
Also undo commuting instructions if it didn't fold an immediate.

[AMDGPU] Narrow lshl from 64 to 32 bit if possible
...
Turn expensive 64 bit shift into 32 bit if shift does not overflow int:
shl (ext x) => zext (shl x)

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.
