GCC unification, part 2. Fix various errors from previous unificaiton.
The previous version of the unified GCC compiler (Android & ChromeOS) caused some ChromeOS tests to fail. It also caused an Android NDK test case to fail. This CL fixes those problems. In particular it does the following: - Fix some file formatting errors from previous unification patch. - Update ChangeLog files to reflect Android backport patches. - Find and incorporate a few missing pieces from the following backports backports from trunk r221007, r221675, r222011, r212011, r214942, r214957, r215012, r215016, r218115, r218733, r218746, r220491. This involved small changes in the following files: gcc/cfghoks.c gcc/cfgloop.c gcc/cfgloop.h gcc/except.c gcc/loop-init.c gcc/omp-low.c - Fix minor Android test case regression introduced in the previous unification patch.
