(build_function_type): Set canonical type.

/* Computes the canonical argument types from the argument type list
ARGTYPES.

- ANY_NONCANONICAL_P points to a boolean that states whether any of
- the other types that work with ARGTYPES (e.g., the return type of
- the function) are non-canonical type nodes. *ANY_NONCANONICAL_P
- will be set TRUE if any of those types or any of the argument types

Returns a canonical argument list, which may be ARGTYPES when the
canonical argument list is unneeded (i.e., *ANY_STRUCTURAL_P is
