[PATCH, rs6000] Correctly set rs6000_always_hint for ppc476

[Peter Bergner]

The 476 cpu has dynamic branch prediction, so we don't want to always
use static branch prediction hints.  Is the following patch ok assuming
my currently running bootstrap/regtesting doesn't uncover any regressions?

Is this appropriate for the 4.6 and 4.5 branches as well?

        * config/rs6000/rs6000.c (rs6000_option_override_internal):
        Set rs6000_always_hint to false for 476.
