Use rtx_insn more within peep2
gcc/ChangeLog:
2014-09-05 David Malcolm <dmalcolm@redhat.com>
* recog.c (peep2_attempt): Strengthen return type from rtx to
rtx_insn *.
(peep2_update_life): Likewise for params "last", "prev", removing
a checked cast made redundant by this.
(peephole2_optimize): Likewise for local "last".
