* rtlanal.c (rtx_unstable_p): The pic register is stable
(within one function) and the actual rtx should be used
when checking the registers.
(rtx_addr_can_trap_p): Pic memory addresses can't trap.
* alias.c (true_dependence, write_dependence_p): Fix
bug in previous patch.
* i386.c (ix86_GOT_alias_set): New.
(legitimize_pic_address): Use it.
* rtlanal.c (rtx_unstable_p): An unchanging MEM is
only stable if its address is stable.
(rtx_varies_p): An unchanging MEM can't vary if
its address doesn't vary.
