See <URL:http://gcc.gnu.org/ml/gcc-patches/2005-04/msg02223.html> #3 and for
example cris_bdap_sign_extend_operand, where this could be used instead of
the match_tests and nested XEXPs. The name "op" and "mode" would refer
to the toplevel of the predicate, while different levels would refer to its own
by TBD. At least opN, modeN would intuitive for numbered predicates.
Perhaps xop, xmode for the "current" level.
