19520 (build_type_attribute_qual_variant): When building an attribute
19521 variant, its canonical type is the non-attribute variant. However,
19522 if the attributes are target-dependent and they differ, we need to
19523 use structural equality checks for this type.
19524 (build_qualified_type): A qualified type is not equivalent to its
19525 unqualified variant; set the canonical type appropriately.
19526 (build_distinct_type_copy): When building a distinct type from
19527 another type, the new type is its own canonical type.
19528 (build_variant_type_copy): When building a new type variant, we
19529 assume that it is equivalent to the original type.
19530 (build_pointer_type_for_mode): When building a pointer type, also
19531 build a canonical type pointer.
19532 (build_reference_type_for_mode): When building a reference type,
19533 also build a canonical type reference.
19534 (build_index_type): When we can't hash an index type (e.g.,
19535 because its maximum value is negative), the index type requires
19536 structural equality tests.
19537 (build_array_type): Build the canonical form of an array type.
19538 (build_function_type): Function types require structural equality,
19539 because they contain default arguments, attributes, etc.
19540 (build_method_type_directly): Ditto for method types.
19541 (build_offset_type): Build the canonical offset type.
