  CodeGen: Remove PointerLikeRegClass

Remove PointerLikeRegClass and the related getPointerRegClass
TargetRegisterInfo hook. This is obsoleted by RegClassByHwMode.
Previously targets would have to map ptr_rc to an assumed pointer
register class by implementing this method, but this is now auto-resolvable
per instruction using RegClassByHwMode.
