[PATCH] Remove unreachable nodes before IPA profile pass (PR ipa/87706).

[Martin Liška]

Hi.

In order to fix the warnings mentioned in the PR, we need
to run remove_unreachable_nodes after early tree passes. That's
however possible only within a IPA pass. Thus I'm calling that
before the profile PASS.

Patch survives regression tests on ppc64le-linux-gnu and majority
of warnings are gone in profiledbootstrap.

Ready for trunk?
Thanks,
Martin
