15286 own canonical type.
15287 (build_type_attribute_qual_variant): When building an attribute
15288 variant, its canonical type is the non-attribute variant. However,
15289 if the attributes are target-dependent and they differ, we need to
15290 use structural equality checks for this type.
15291 (build_qualified_type): A qualified type is not equivalent to its
15292 unqualified variant; set the canonical type appropriately.
15293 (build_distinct_type_copy): When building a distinct type from
15294 another type, the new type is its own canonical type.
15295 (build_variant_type_copy): When building a new type variant, we

15298 build a canonical type pointer.
15299 (build_reference_type_for_mode): When building a reference type,
15300 also build a canonical type reference.
15301 (build_index_type): When we can't hash an index type (e.g.,
15302 because its maximum value is negative), the index type requires
15303 structural equality tests.
15304 (build_array_type): Build the canonical form of an array type.
15305 (build_function_type): Function types require structural equality,
15306 because they contain default arguments, attributes, etc.
15307 (build_method_type_directly): Ditto for method types.
15308 (build_offset_type): Build the canonical offset type.
