Marek Olsak 7ed6b2f414 AMDGPU/SI: select S_ABS_I32 when possible (v2) 
v2: added more tests, moved the SALU->VALU conversion to a separate function

It looks like it's not possible to get subregisters in the S_ABS lowering
code, and I don't feel like guessing without testing what the correct code
would look like.
