params 2 and 3 of reg_set_between_p

gcc/ChangeLog:
	* config/alpha/alpha.c (alpha_ra_ever_killed): Replace NULL_RTX
	with NULL when dealing with an insn.
	* config/sh/sh.c (sh_reorg): Strengthen local "last_float_move"
	from rtx to rtx_insn *.
	* rtl.h (reg_set_between_p): Strengthen params 2 and 3 from
	const_rtx to const rtx_insn *.
	* rtlanal.c (reg_set_between_p): Likewise, removing a checked cast.
