+ functions and to maybe_push_res_to_seq in the publicly-facing
+ operation-specific gimple_simplify overloads.

+ parameter. Update call to gimple_simplify.

+ with a single gimple_match_op *. Update calls to mprts_hook,
+ build_call_internal and gimple_simplified_result_is_gimple_val.
+ Factor out code that is common to the tree_code and combined_fn cases.
+ * genmatch.c (expr::gen_transform): Replace tem_code and
+ tem_ops with a gimple_match_op called tem_op. Update calls
+ to the gimple_resimplify functions and maybe_push_res_to_seq.

+ res_ops. Update call to the gimple_resimplify functions.
+ (dt_simplify::gen): Pass res_op instead of res_code and res_ops.
+ (decision_tree::gen): Make the functions take a gimple_match_op *
+ called res_op instead of separate res_code and res_ops parameters.
+ Update call accordingly.
+ * gimple-fold.c (replace_stmt_with_simplification): Replace rcode
+ and ops with a single res_op parameter. Update calls to
+ maybe_build_generic_op and maybe_push_res_to_seq.

+ replace_stmt_with_simplification.
+ (gimple_fold_stmt_to_constant_1): Update calls to gimple_simplify
+ and gimple_simplified_result_is_gimple_val.

+ and to gimple_simplified_result_is_gimple_val.
+ (vn_nary_simplify): Update call to vn_nary_build_or_lookup_1.
+ Use gimple_match_op::MAX_NUM_OPS instead of a hard-coded 3.
