25401 own canonical type.
25402 (build_type_attribute_qual_variant): When building an attribute
25403 variant, its canonical type is the non-attribute variant. However,
25404 if the attributes are target-dependent and they differ, we need to
25405 use structural equality checks for this type.
25406 (build_qualified_type): A qualified type is not equivalent to its
25407 unqualified variant; set the canonical type appropriately.

25409 another type, the new type is its own canonical type.

25414 (build_reference_type_for_mode): When building a reference type,
25415 also build a canonical type reference.
25416 (build_index_type): When we can't hash an index type (e.g.,
25417 because its maximum value is negative), the index type requires
25418 structural equality tests.
25419 (build_array_type): Build the canonical form of an array type.
25420 (build_function_type): Function types require structural equality,
25421 because they contain default arguments, attributes, etc.
25422 (build_method_type_directly): Ditto for method types.
25423 (build_offset_type): Build the canonical offset type.
