18232 * c-common.c (c_common_nodes_and_builtins): Since variants of

18244 own canonical type.
18245 (build_type_attribute_qual_variant): When building an attribute
18246 variant, its canonical type is the non-attribute variant. However,
18247 if the attributes are target-dependent and they differ, we need to
18248 use structural equality checks for this type.
18249 (build_qualified_type): A qualified type is not equivalent to its
18250 unqualified variant; set the canonical type appropriately.
18251 (build_distinct_type_copy): When building a distinct type from
18252 another type, the new type is its own canonical type.
18253 (build_variant_type_copy): When building a new type variant, we
18254 assume that it is equivalent to the original type.
18255 (build_pointer_type_for_mode): When building a pointer type, also
18256 build a canonical type pointer.
18257 (build_reference_type_for_mode): When building a reference type,
18258 also build a canonical type reference.
18259 (build_index_type): When we can't hash an index type (e.g.,
18260 because its maximum value is negative), the index type requires
18261 structural equality tests.
18262 (build_array_type): Build the canonical form of an array type.
18263 (build_function_type): Function types require structural equality,
18264 because they contain default arguments, attributes, etc.
18265 (build_method_type_directly): Ditto for method types.
