* params.def (PARAM_VERIFY_CANONICAL_TYPES): Remove.
(PARAM_USE_CANONICAL_TYPES): New; decides whether to use canonical
types or not.
* params.h (VERIFY_CANONICAL_TYPES): Remove.
(USE_CANONICAL_TYPES): New.
* doc/invoke.texi (verify-canonical-types): Remove.
(use-canonical-types): Add.

* typeck.c (comptypes): When USE_CANONICAL_TYPES, use the
canonical types; otherwise, fall back to structural type
comparisons. If ENABLE_CHECKING and USE_CANONICAL_TYPES, give an
internal compiler error if the canonical types are wrong.
