10810         own canonical type.
10811         (build_type_attribute_qual_variant): When building an attribute
10812         variant, its canonical type is the non-attribute variant. However,
10813         if the attributes are target-dependent and they differ, we need to
10814         use structural equality checks for this type.
10815         (build_qualified_type): A qualified type is not equivalent to its
10816         unqualified variant; set the canonical type appropriately.

10818         another type, the new type is its own canonical type.

10822         build a canonical type pointer.

10824         also build a canonical type reference.
10825         (build_index_type): When we can't hash an index type (e.g.,
10826         because its maximum value is negative), the index type requires
10827         structural equality tests.
10828         (build_array_type): Build the canonical form of an array type.
10829         (build_function_type): Function types require structural equality,
10830         because they contain default arguments, attributes, etc.
10831         (build_method_type_directly): Ditto for method types.
10832         (build_offset_type): Build the canonical offset type.

10844         parameter for verifying canonical types.
