21611 (build_type_attribute_qual_variant): When building an attribute
21612 variant, its canonical type is the non-attribute variant. However,
21613 if the attributes are target-dependent and they differ, we need to
21614 use structural equality checks for this type.
21615 (build_qualified_type): A qualified type is not equivalent to its
21616 unqualified variant; set the canonical type appropriately.
21617 (build_distinct_type_copy): When building a distinct type from
21618 another type, the new type is its own canonical type.
21619 (build_variant_type_copy): When building a new type variant, we
21620 assume that it is equivalent to the original type.
21621 (build_pointer_type_for_mode): When building a pointer type, also
21622 build a canonical type pointer.
21623 (build_reference_type_for_mode): When building a reference type,
21624 also build a canonical type reference.
21625 (build_index_type): When we can't hash an index type (e.g.,
21626 because its maximum value is negative), the index type requires
21627 structural equality tests.
21628 (build_array_type): Build the canonical form of an array type.
21629 (build_function_type): Function types require structural equality,
21630 because they contain default arguments, attributes, etc.
21631 (build_method_type_directly): Ditto for method types.
21632 (build_offset_type): Build the canonical offset type.
