Re: Profiling gcc building Mozilla

The HAVE_POST_INCREMENT and HAVE_POST_DECREMENT defines for the GCC's
ia64 backend resulted in a large amount (17.5%) being spend in the
ia64_secondary_reload_class, regclass, and true_regnum functions for
cc1plus.  There is a triple nested loop in regclass that is enabled
bout the defines.

It looks like this was addressed already.

        * regclass.c (init_reg_autoinc): New function.
        (regclass): Move initialization of forbidden_inc_dec_class from
        here...
        (init_regs): to here. Avoids reinitialization for each function,
        saving compilation time.
