23645 (build_type_attribute_qual_variant): When building an attribute
23646 variant, its canonical type is the non-attribute variant. However,
23647 if the attributes are target-dependent and they differ, we need to
23648 use structural equality checks for this type.
23649 (build_qualified_type): A qualified type is not equivalent to its
23650 unqualified variant; set the canonical type appropriately.
23651 (build_distinct_type_copy): When building a distinct type from
23652 another type, the new type is its own canonical type.
23653 (build_variant_type_copy): When building a new type variant, we
23654 assume that it is equivalent to the original type.
23655 (build_pointer_type_for_mode): When building a pointer type, also
23656 build a canonical type pointer.
23657 (build_reference_type_for_mode): When building a reference type,
23658 also build a canonical type reference.
23659 (build_index_type): When we can't hash an index type (e.g.,
23660 because its maximum value is negative), the index type requires
23661 structural equality tests.
23662 (build_array_type): Build the canonical form of an array type.
23663 (build_function_type): Function types require structural equality,
23664 because they contain default arguments, attributes, etc.
23665 (build_method_type_directly): Ditto for method types.
23666 (build_offset_type): Build the canonical offset type.
