29485 own canonical type.
29486 (build_type_attribute_qual_variant): When building an attribute
29487 variant, its canonical type is the non-attribute variant. However,
29488 if the attributes are target-dependent and they differ, we need to
29489 use structural equality checks for this type.
29490 (build_qualified_type): A qualified type is not equivalent to its
29491 unqualified variant; set the canonical type appropriately.
29492 (build_distinct_type_copy): When building a distinct type from
29493 another type, the new type is its own canonical type.
29494 (build_variant_type_copy): When building a new type variant, we
29495 assume that it is equivalent to the original type.
29496 (build_pointer_type_for_mode): When building a pointer type, also
29497 build a canonical type pointer.
29498 (build_reference_type_for_mode): When building a reference type,
29499 also build a canonical type reference.
29500 (build_index_type): When we can't hash an index type (e.g.,
29501 because its maximum value is negative), the index type requires
29502 structural equality tests.
29503 (build_array_type): Build the canonical form of an array type.
29504 (build_function_type): Function types require structural equality,
29505 because they contain default arguments, attributes, etc.
29506 (build_method_type_directly): Ditto for method types.
