[PATCH 137/236] config/iq2000: Use rtx_insn

[David Malcolm <dmalcolm at redhat dot com>]

gcc/
	* config/iq2000/iq2000-protos.h (final_prescan_insn): Strengthen
	first param from rtx to rtx_insn *.
	(iq2000_adjust_insn_length): Likewise.
	(iq2000_output_conditional_branch): Likewise.
	* config/iq2000/iq2000.c (final_prescan_insn): Likewise for param
	"insn" and local "nop_insn".
	(iq2000_annotate_frame_insn): Likewise for param "insn".
	(iq2000_expand_prologue): Likewise for both locals "insn".
	(iq2000_adjust_insn_length): Likewise for param "insn".
	(iq2000_output_conditional_branch): Likewise.
