6010         own canonical type.
6011         (build_type_attribute_qual_variant): When building an attribute
6012         variant, its canonical type is the non-attribute variant. However,
6013         if the attributes are target-dependent and they differ, we need to
6014         use structural equality checks for this type.
6015         (build_qualified_type): A qualified type is not equivalent to its
6016         unqualified variant; set the canonical type appropriately.

6018         another type, the new type is its own canonical type.

6024         also build a canonical type reference.
6025         (build_index_type): When we can't hash an index type (e.g.,
6026         because its maximum value is negative), the index type requires
6027         structural equality tests.
6028         (build_array_type): Build the canonical form of an array type.
6029         (build_function_type): Function types require structural equality,
6030         because they contain default arguments, attributes, etc.
6031         (build_method_type_directly): Ditto for method types.
6032         (build_offset_type): Build the canonical offset type.
