Carl Ritson 5bc703f755 [AMDGPU] Replace getPhysRegClass with getPhysRegBaseClass ...

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.
