Matt Arsenault 6c29c5acfe 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.

Matt Arsenault 3dbeefa978 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).

To shrink to VOP2 the input carry must also be VCC.

Matt Arsenault 28bd4cbeaf AMDGPU: Fix breaking VOP3 v_add_i32s
This was shrinking the instruction even though the carry output
register was a virtual register, not known VCC.
