rs6000: rs6000_dbx_register_number for fp/ap/mq
The frame pointer and the argument pointer aren't real registers. MQ
was a register on old POWER. All three are still used as arguments to
rs6000_dbx_register_number during initialisation. If we handle them
explicitly we can do a gcc_unreachable to catch other unexpected
registers.
* config/rs6000/rs6000.c (rs6000_dbx_register_number): Handle
FRAME_POINTER_REGNUM, ARG_POINTER_REGNUM, and 64 (which was MQ).
