[PATCH 1/2] use rtx_insn * more

[tsaunders at mozilla dot com]

From: Trevor Saunders <tsaunders@mozilla.com>

Hi,

pretty trivial, but not quiet just changing the types of variables.
bootstrapped + regtested on x86_64-unknown-linux-gnu, and run through
config-list.mk with a couple other patches. ok?

gcc/ChangeLog:

2014-09-11  Trevor Saunders  <tsaunders@mozilla.com>

	* config/mn10300/mn10300.c (mn10300_insert_setlb_lcc): Assign the
	result of emit_jump_insn_before to a new variable.
	* jump.c (mark_jump_label): Change the type of insn to rtx_insn *.
	(mark_jump_label_1): Likewise.
	(mark_jump_label_asm): Likewise.
	* reload1.c (gen_reload): Change type of tem to rtx_insn *.
	* rtl.h (mark_jump_label): Adjust.
