rtlanal.c: Use rtx_insn

gcc/
2014-08-22  David Malcolm  <dmalcolm@redhat.com>

	* rtlanal.c (reg_used_between_p): Strengthen local "insn" from rtx
	to rtx_insn *.
	(reg_set_between_p): Strengthen local "insn" from const_rtx to
	const rtx_insn *.
	(modified_between_p): Strengthen local "insn" from rtx to
	rtx_insn *.
	(remove_reg_equal_equiv_notes_for_regno): Likewise.
	(keep_with_call_p): Strengthen local "i2" from const_rtx to
	const rtx_insn *.
