Remove CC0
This removes CC0 and all directly related infrastructure.
CC_STATUS, CC_STATUS_MDEP, CC_STATUS_MDEP_INIT, and NOTICE_UPDATE_CC
are deleted and poisoned. CC0 is only deleted (some targets use that
name for something else). HAVE_cc0 is automatically generated, and we
no longer will do that after this patch.
CC_STATUS_INIT is suggested in final.c to also be useful for ports that
are not CC0, and at least arm seems to use it for something. So I am
leaving that alone, but most targets that have it could remove it.
