  Log Message:
  -----------
  [AMDGPU] Replace getPhysRegClass with getPhysRegBaseClass

Accelerate finding the base class for a physical register by
building a statically mapping table from physical registers
to base classes using TableGen.

Replace uses of SIRegisterInfo::getPhysRegClass with
TargetRegisterInfo::getPhysRegBaseClass in order to use
the computed table.
