17840 * c-common.c (c_common_nodes_and_builtins): Since variants of

17853 (build_type_attribute_qual_variant): When building an attribute
17854 variant, its canonical type is the non-attribute variant. However,
17855 if the attributes are target-dependent and they differ, we need to
17856 use structural equality checks for this type.
17857 (build_qualified_type): A qualified type is not equivalent to its
17858 unqualified variant; set the canonical type appropriately.
17859 (build_distinct_type_copy): When building a distinct type from
17860 another type, the new type is its own canonical type.
17861 (build_variant_type_copy): When building a new type variant, we
17862 assume that it is equivalent to the original type.
17863 (build_pointer_type_for_mode): When building a pointer type, also
17864 build a canonical type pointer.
17865 (build_reference_type_for_mode): When building a reference type,
17866 also build a canonical type reference.
17867 (build_index_type): When we can't hash an index type (e.g.,
17868 because its maximum value is negative), the index type requires
17869 structural equality tests.
17870 (build_array_type): Build the canonical form of an array type.
17871 (build_function_type): Function types require structural equality,
17872 because they contain default arguments, attributes, etc.
17873 (build_method_type_directly): Ditto for method types.
