AMDGPU target specific MCExpr operations.
Takes in a minimum of 1 argument to be used with an operation. The supported operations are:

Allow delayed MCExpr resolve of ExtraSGPRs (in case VCCUsed or FlatScrUsed are unresolvable but needed for further MCExprs).

Mimics GCNSubtarget::computeOccupancy for MCExpr.
Remove dependency on GCNSubtarget and depend only only the necessary values for said occupancy computation. Should match computeOccupancy implementation without passing STM
on.
