12502 own canonical type.
12503 (build_type_attribute_qual_variant): When building an attribute
12504 variant, its canonical type is the non-attribute variant. However,
12505 if the attributes are target-dependent and they differ, we need to
12506 use structural equality checks for this type.
12507 (build_qualified_type): A qualified type is not equivalent to its
12508 unqualified variant; set the canonical type appropriately.
12509 (build_distinct_type_copy): When building a distinct type from
12510 another type, the new type is its own canonical type.
12511 (build_variant_type_copy): When building a new type variant, we
12512 assume that it is equivalent to the original type.
12513 (build_pointer_type_for_mode): When building a pointer type, also

12515 (build_reference_type_for_mode): When building a reference type,
12516 also build a canonical type reference.
12517 (build_index_type): When we can't hash an index type (e.g.,
12518 because its maximum value is negative), the index type requires
12519 structural equality tests.
12520 (build_array_type): Build the canonical form of an array type.
12521 (build_function_type): Function types require structural equality,
12522 because they contain default arguments, attributes, etc.
12523 (build_method_type_directly): Ditto for method types.
12524 (build_offset_type): Build the canonical offset type.
