This would be a lot easier to review, if each of this change is
actually moved to the corresponding patch passing retaddr to the
exception function. In addition to that you have left a few call to
gen_update_cc_op(s). They are not needed if the helper doesn't read
not write cc_op.
Finally, this patch misses at least helper_fbld_ST0.
