14611         (build_type_attribute_qual_variant): When building an attribute
14612         variant, its canonical type is the non-attribute variant. However,
14613         if the attributes are target-dependent and they differ, we need to
14614         use structural equality checks for this type.
14615         (build_qualified_type): A qualified type is not equivalent to its
14616         unqualified variant; set the canonical type appropriately.
14617         (build_distinct_type_copy): When building a distinct type from
14618         another type, the new type is its own canonical type.

14620         assume that it is equivalent to the original type.

14622         build a canonical type pointer.

14624         also build a canonical type reference.
14625         (build_index_type): When we can't hash an index type (e.g.,
14626         because its maximum value is negative), the index type requires
14627         structural equality tests.
14628         (build_array_type): Build the canonical form of an array type.
14629         (build_function_type): Function types require structural equality,
14630         because they contain default arguments, attributes, etc.
14631         (build_method_type_directly): Ditto for method types.
14632         (build_offset_type): Build the canonical offset type.

14644         parameter for verifying canonical types.
