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.
