Update rs6000.c's pass_analyze_swaps to use rtx_insn

gcc/
	* config/rs6000/rs6000.c (class swap_web_entry): Strengthen field
	"insn" from rtx to rtx_insn *.
	(permute_load): Likewise for param "insn".
	(permute_store): Likewise.
	(handle_special_swappables): Likewise for local "insn".
	(replace_swap_with_copy): Likewise for locals "insn" and
	"new_insn".
	(rs6000_analyze_swaps): Likewise for local "insn".
