* optabs.h (unknown_optab): New.
* builtins.c (interclass_mathfn_icode): Use it.
* dojump.c (do_compare_rtx_and_jump): Likewise.
* optabs.c (optab_for_tree_code, expand_binop): Likewise.
* tree-vect-generic.c (add_rshift, expand_vector_divmod): Likewise.
(expand_vector_operations_1): Likewise.
* tree-vect-patterns.c (vect_recog_divmod_pattern): Likewise.
