Constructing Target triple with `ObjectFile::makeTriple` instead of just with `Arch` and leaving the rest unknown. Also creating the subtarget with the `CPU`. AMDGPU needs the full triple and `CPU` to disassemble correctly. To run a full test, also fixed a failure in `SIPreAllocateWWMRegs` with the `$noreg` operand in `DBG_VALUE`. --------- Co-authored-by: Matt Arsenault <arsenm2@gmail.com>
