[AMDGPU] Cleanup assumptions about generated subregs
We are using countPopulation on a LaneBitmask to determine
a number of registers it covers. This is the assumption which
does not necessarily need to be true. It is not changed but
factored into a single call SIRegisterInfo::getNumCoveredRegs().
Some other places are cleaned up with respect to assumptions
about subreg indexes values and tablegen behavior.
