Drop uncast_insn from param 1 of final_scan_insn

gcc/ChangeLog
2014-09-05  David Malcolm  <dmalcolm@redhat.com>

	* output.h (final_scan_insn): Strengthen first param from rtx to
	rtx_insn *.

	* final.c (final_scan_insn): Likewise, renaming it back from
	"uncast_insn" to "insn", eliminating the checked cast.

	* config/h8300/h8300.md (define_insn "jump"): Replace local rtx
	"vec" with an rtx_sequence * "seq", taking a copy of
	"final_sequence", and using methods of "seq" for clarity, and for
	type-safety in the calls to final_scan_insn.
	* config/mips/mips.c (mips_output_conditional_branch): Use methods
	of "final_sequence" for clarity, and for type-safety in the call to
	final_scan_insn.
	* config/sh/sh.c (print_slot): Strengthen param from rtx to
	rtx_sequence * and rename from "insn" to "seq".
