* rtl.def (match_code): Add second argument.
* genpreds.c (write_extract_subexp): New function.
(write_match_code): Add path argument. Use write_extract_subexp.
(write_predicate_expr): Pass path to write_match_code.
(mark_mode_tests): MATCH_CODE applied to a subexpression does
not perform a mode test.
* genrecog.c (compute_predicate_codes): MATCH_CODE applied to
a subexpression does not constrain the top-level code set.
* read-rtl.c (read_rtx_variadic): New function.
(read_rtx_1): Use it; allow AND and IOR to be variadic.
* doc/md.texi: Document new notation.
* config/i386/predicates.md (cmpsi_operand_1): Fold into ...
(cmpsi_operand): ... here, using new notation.
