	* combine.c (can_combine_def_p): Don't check the value of
	HARD_FRAME_POINTER_IS_FRAME_POINTER with the preprocessor.
	(combinable_i3pat): Likewise.
	(mark_used_regs_combine): Likewise.
	* regrename.c (rename_chains): Likewise.
	* reload.c (find_reloads_address): Likewise.
	* sel-sched.c (mark_unavailable_hard_regs): Likewise.
