24152 own canonical type.
24153 (build_type_attribute_qual_variant): When building an attribute
24154 variant, its canonical type is the non-attribute variant. However,
24155 if the attributes are target-dependent and they differ, we need to
24156 use structural equality checks for this type.
24157 (build_qualified_type): A qualified type is not equivalent to its
24158 unqualified variant; set the canonical type appropriately.
24159 (build_distinct_type_copy): When building a distinct type from
24160 another type, the new type is its own canonical type.

24163 (build_pointer_type_for_mode): When building a pointer type, also

24165 (build_reference_type_for_mode): When building a reference type,
24166 also build a canonical type reference.
24167 (build_index_type): When we can't hash an index type (e.g.,
24168 because its maximum value is negative), the index type requires
24169 structural equality tests.
24170 (build_array_type): Build the canonical form of an array type.
24171 (build_function_type): Function types require structural equality,
24172 because they contain default arguments, attributes, etc.
24173 (build_method_type_directly): Ditto for method types.
24174 (build_offset_type): Build the canonical offset type.
