REG_CLASS_CONTENTS initializer fix


Brought to light by the T3 port that was posted a while ago.

We have it documented that we only take 32 bits per initializer
from REG_CLASS_CONTENTS, but we weren't actually honoring that.

Sanity checked on alphaev56 linux.

        * regclass.c (init_reg_sets): Use only 32 bits per initializer
        from int_reg_class_contents.
