profile-count.c (safe_scale_64bit): Fix GCC4.x path.

* profile-count.c (safe_scale_64bit): Fix GCC4.x path.
(profile_probability): Set max_probability
to (uint32_t) 1 << (n_bits - 2) and update accessors to avoid overlfows
in temporaries.
* profile-count.c (profile_probability::differs_from_p): Do not
rely on max_probaiblity == 10000

* gcc.dg/predict-13.c: Update template for probaility change.
* gcc.dg/predict-8.c: Likewise.
