14397 * c-common.c (c_common_nodes_and_builtins): Since variants of

14409 own canonical type.
14410 (build_type_attribute_qual_variant): When building an attribute
14411 variant, its canonical type is the non-attribute variant. However,
14412 if the attributes are target-dependent and they differ, we need to
14413 use structural equality checks for this type.
14414 (build_qualified_type): A qualified type is not equivalent to its
14415 unqualified variant; set the canonical type appropriately.
14416 (build_distinct_type_copy): When building a distinct type from
14417 another type, the new type is its own canonical type.
14418 (build_variant_type_copy): When building a new type variant, we
14419 assume that it is equivalent to the original type.
14420 (build_pointer_type_for_mode): When building a pointer type, also
14421 build a canonical type pointer.
14422 (build_reference_type_for_mode): When building a reference type,
14423 also build a canonical type reference.
14424 (build_index_type): When we can't hash an index type (e.g.,
14425 because its maximum value is negative), the index type requires
14426 structural equality tests.
14427 (build_array_type): Build the canonical form of an array type.
14428 (build_function_type): Function types require structural equality,
14429 because they contain default arguments, attributes, etc.
14430 (build_method_type_directly): Ditto for method types.
