[PATCH, committed] insn_extract takes an rtx_insn

[David Malcolm]

The attached trivial patch strengthens the param of the generated
"insn_extract" function, from rtx to rtx_insn *, and thus falls under
the pre-approval granted by Jeff here:
  https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01310.html

Bootstrapped on x86_64-unknown-linux-gnu (Fedora 20), and has been
rebuilt as part of a config-list.mk build for all working configurations
(albeit with other patches for the latter case).

Committed to trunk as r215132
