Strengthen various insn emission functions 

gcc/
2014-08-26  David Malcolm  <dmalcolm@redhat.com>

	* rtl.h (push_to_sequence): Strengthen param from rtx to
	rtx_insn *.
	(push_to_sequence2): Likewise for both params.
	(delete_insns_since): Likewise for param.
	(reorder_insns_nobb): Likewise for all three params.
	(set_new_first_and_last_insn): Likewise for both params.

	* emit-rtl.h (set_first_insn): Strengthen param "insn" from rtx to
	rtx_insn *.  Remove now-redundant cast.
	(set_last_insn): Likewise.

	* builtins.c (expand_builtin_return): Strengthen local
	"call_fusage" from rtx to rtx_insn *.
	* cfgrtl.c (create_basic_block_structure): Likewise for local
	"after".
	* emit-rtl.c (set_new_first_and_last_insn): Likewise for params
	"first", "last" and local "insn".
	(delete_insns_since): Likewise for param "from".
	(reorder_insns_nobb): Likewise for params "from", "to", "after"
	and local "x".
	(push_to_sequence): Likewise for param "first" and local "last".
	(push_to_sequence2): Likewise for params "first" and "last".
	* lra.c (emit_add3_insn): Likewise for local "last".
	(lra_emit_add): Likewise.
	* lra-constraints.c (base_to_reg): Likewise for locals "insn",
	"last_insn".
	(process_address_1): Likewise for locals "insn", last".
	* modulo-sched.c (ps_first_note): Likewise for return type.
	* optabs.c (expand_binop_directly): Likewise for param "last".
