Synchronize internal and external version. Merge the following patches:
-Added a more helpful error message when the profile is corrupted.
-Added check for abnormal ssa names in the analysis phase of the vectorizer
so that it prevents a potential ICE.
-Replace floating-point calculations with fixed-point calculations when
computing inlining priority to eliminate floating-point non-determinism
on 32-bit x86.
-Use .init_array/.fini_array sections instead of .ctor/.dtor when
configured with --enable-initfini-array.
