function.c and shrink-wrap.*: more rtx_insn

gcc/
	* function.c (thread_prologue_and_epilogue_insns): Likewise for
	locals "returnjump", "epilogue_end", "insn", "next".

	* shrink-wrap.h (get_unconverted_simple_return): Strengthen param
	"returnjump" from rtx * to rtx_insn **.
	* shrink-wrap.c (get_unconverted_simple_return): Likewise.
