22437 (build_type_attribute_qual_variant): When building an attribute
22438 variant, its canonical type is the non-attribute variant. However,
22439 if the attributes are target-dependent and they differ, we need to
22440 use structural equality checks for this type.
22441 (build_qualified_type): A qualified type is not equivalent to its
22442 unqualified variant; set the canonical type appropriately.
22443 (build_distinct_type_copy): When building a distinct type from
22444 another type, the new type is its own canonical type.
22445 (build_variant_type_copy): When building a new type variant, we
22446 assume that it is equivalent to the original type.
22447 (build_pointer_type_for_mode): When building a pointer type, also
22448 build a canonical type pointer.
22449 (build_reference_type_for_mode): When building a reference type,
22450 also build a canonical type reference.
22451 (build_index_type): When we can't hash an index type (e.g.,
22452 because its maximum value is negative), the index type requires
22453 structural equality tests.
22454 (build_array_type): Build the canonical form of an array type.
22455 (build_function_type): Function types require structural equality,
22456 because they contain default arguments, attributes, etc.
22457 (build_method_type_directly): Ditto for method types.
