28593 (build_type_attribute_qual_variant): When building an attribute
28594 variant, its canonical type is the non-attribute variant. However,
28595 if the attributes are target-dependent and they differ, we need to
28596 use structural equality checks for this type.
28597 (build_qualified_type): A qualified type is not equivalent to its
28598 unqualified variant; set the canonical type appropriately.
28599 (build_distinct_type_copy): When building a distinct type from
28600 another type, the new type is its own canonical type.
28601 (build_variant_type_copy): When building a new type variant, we
28602 assume that it is equivalent to the original type.
28603 (build_pointer_type_for_mode): When building a pointer type, also
28604 build a canonical type pointer.
28605 (build_reference_type_for_mode): When building a reference type,
28606 also build a canonical type reference.
28607 (build_index_type): When we can't hash an index type (e.g.,
28608 because its maximum value is negative), the index type requires
28609 structural equality tests.
28610 (build_array_type): Build the canonical form of an array type.
28611 (build_function_type): Function types require structural equality,
28612 because they contain default arguments, attributes, etc.
28613 (build_method_type_directly): Ditto for method types.
