try_split returns an rtx_insn
2014-08-21 David Malcolm <dmalcolm@redhat.com>
* rtl.h (try_split): Strengthen return type from rtx to rtx_insn *.
* emit-rtl.c (try_split): Likewise, also for locals "before" and
"after". For now, don't strengthen param "trial", which requires
adding checked casts when returning it.
