config/epiphany: Use rtx_insn

gcc/
	* config/epiphany/epiphany-protos.h (epiphany_final_prescan_insn):
	Strengthen first param "insn" from rtx to rtx_insn *.

	* config/epiphany/epiphany.c (epiphany_final_prescan_insn):
	Likewise.
	(frame_insn): Likewise for return type.  Introduce local "insn"
	for use in place of local "x" for use as an rtx_insn *.
	(frame_move_insn): Strengthen return type from rtx to rtx_insn *.
	(epiphany_expand_prologue): Likewise for local "insn".
	* config/epiphany/mode-switch-use.c (insert_uses): Likewise.
	* config/epiphany/resolve-sw-modes.c
	(pass_resolve_sw_modes::execute): Likewise for locals "insn" and
	"seq".
