INSN_LOCATION takes an rtx_insn

gcc/ChangeLog:
2014-09-09  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (INSN_LOCATION): Strengthen param from const_rtx to
	const rtx_insn *, and from rtx to rtx_insn * for the other
	overloaded variant.
	(RTL_LOCATION): Add a checked cast to rtx_insn * when invoking
	INSN_LOCATION, since we know INSN_P holds.
	(insn_line): Strengthen param from const_rtx to const rtx_insn *.
	(insn_file): Likewise.
	(insn_scope): Likewise.
	(insn_location): Likewise.

	* config/mips/mips.c (mips16_gp_pseudo_reg): Strengthen local
	"insn" from rtx to rtx_insn *, introducing a new local rtx "set"
	for the result of gen_load_const_gp.
	* config/rs6000/rs6000-protos.h (output_call): Strengthen first
	param from rtx to rtx_insn *.
	* config/rs6000/rs6000.c (output_call): Likewise.
	* dwarf2out.c (dwarf2out_var_location): Likewise for local "prev",
	introducing a checked cast to rtx_sequence * and use of the insn
	method.
	* emit-rtl.c (emit_copy_of_insn_after): Strengthen both params
	from rtx to rtx_insn *.
	(insn_scope): Strengthen param from const_rtx to const rtx_insn *.
	(insn_line): Likewise.
	(insn_file): Likewise.
	(insn_location): Likewise.
	* emit-rtl.h (emit_copy_of_insn_after): Strengthen both params
	from rtx to rtx_insn *.
	* print-rtl.c (print_rtx): Introduce local "in_insn" via a checked
	cast, using it for calls to INSN_HAS_LOCATION and insn_location.
	* recog.c (peep2_attempt): Introduce local rtx_insn * "peepinsn"
	via a checked cast.
	* reorg.c (relax_delay_slots): Strengthen locals named "after"
	from rtx to rtx_insn *; use methods of "pat" for type-safety.
