6707         own canonical type.
6708         (build_type_attribute_qual_variant): When building an attribute
6709         variant, its canonical type is the non-attribute variant. However,
6710         if the attributes are target-dependent and they differ, we need to
6711         use structural equality checks for this type.
6712         (build_qualified_type): A qualified type is not equivalent to its
6713         unqualified variant; set the canonical type appropriately.

6715         another type, the new type is its own canonical type.

6721         also build a canonical type reference.
6722         (build_index_type): When we can't hash an index type (e.g.,
6723         because its maximum value is negative), the index type requires
6724         structural equality tests.
6725         (build_array_type): Build the canonical form of an array type.
6726         (build_function_type): Function types require structural equality,
6727         because they contain default arguments, attributes, etc.
6728         (build_method_type_directly): Ditto for method types.
6729         (build_offset_type): Build the canonical offset type.
