I know we check regno < FIRST_PSEUDO_REGISTER almost everywhere
but I'm kinda hoping to convince people that the HARD_REGISTER_P
and HARD_REGISTER_NUM_P checks are more readable... ;-)

Good idea. Here's the mips port done. The remaining uses of FIRST_PSEUDO_REGISTER are all in loops.

Tested on mipsisa64-elf and committed.
