I led Andrew astray in telling him to just initialize call_really_used_regs
to call_used_regs.  The x86 port initializes call_used_regs to a bitmask and
cleans things up in CONDITIONAL_REGISTER_USAGE.


r~


        * regclass.c (call_really_used_regs): Conditionally define.
        (init_reg_sets_1): Don't use it if not defined.
        (fix_register): Similarly, don't set it.
