31244 * c-common.c (c_common_nodes_and_builtins): Since variants of

31257 (build_type_attribute_qual_variant): When building an attribute
31258 variant, its canonical type is the non-attribute variant. However,
31259 if the attributes are target-dependent and they differ, we need to
31260 use structural equality checks for this type.
31261 (build_qualified_type): A qualified type is not equivalent to its
31262 unqualified variant; set the canonical type appropriately.
31263 (build_distinct_type_copy): When building a distinct type from
31264 another type, the new type is its own canonical type.
31265 (build_variant_type_copy): When building a new type variant, we
31266 assume that it is equivalent to the original type.
31267 (build_pointer_type_for_mode): When building a pointer type, also
31268 build a canonical type pointer.
31269 (build_reference_type_for_mode): When building a reference type,
31270 also build a canonical type reference.
31271 (build_index_type): When we can't hash an index type (e.g.,
31272 because its maximum value is negative), the index type requires
31273 structural equality tests.
31274 (build_array_type): Build the canonical form of an array type.
31275 (build_function_type): Function types require structural equality,
31276 because they contain default arguments, attributes, etc.
31277 (build_method_type_directly): Ditto for method types.
