[regrename][sel-sched] Fix bogus use of HARD_FRAME_POINTER_REGNUM (was: Fix arm bootstrap)

Browse source 
* regrename.c (rename_chains): Check
	HARD_FRAME_POINTER_IS_FRAME_POINTER rather than
	HARD_FRAME_POINTER_REGNUM when picking unavailable registers.
	* sel-sched.c (mark_unavailable_hard_regs): Likewise.
