[PATCH 0/5] More rtx->rtx_insn * cleanups

[David Malcolm <dmalcolm at redhat dot com>]

This patch kit strengthens various parameters in emit-rtl.h/c from
rtx to rtx_insn *, eliminating 14 "as_a"/"safe_as_a" casts from
emit-rtl.c (though requiring a few new ones elsewhere).

It's effectively one patch; I've split it up for ease of review.

Nearly all of it is trivial, and would be covered by the pre-approval
here:
  https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01310.html

However, some of the sh.c changes appear to need review.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.

Successfully built "cc1" binaries on all 198 configurations in
contrib/config-list.mk.

OK for trunk?
