AMDGPU/GlobalISel: Regbanklegalize rules for G_UNMERGE_VALUES ( #171653 )
...
Move G_UNMERGE_VALUES handling to AMDGPURegBankLegalizeRules.cpp.
Fix sgpr S16 unmerge by lowering using shift and using S32.
Previously sgpr S16 unmerge was selected using _lo16 and _hi16 subreg
indexes which are exclusive to vgpr register classes.
For remaing cases we do trivial mapping, assigns same reg bank
to all operands, vgpr or sgpr.
