12362 * c-common.c (c_common_nodes_and_builtins): Since variants of

12374 own canonical type.
12375 (build_type_attribute_qual_variant): When building an attribute
12376 variant, its canonical type is the non-attribute variant. However,
12377 if the attributes are target-dependent and they differ, we need to
12378 use structural equality checks for this type.
12379 (build_qualified_type): A qualified type is not equivalent to its
12380 unqualified variant; set the canonical type appropriately.
12381 (build_distinct_type_copy): When building a distinct type from
12382 another type, the new type is its own canonical type.
12383 (build_variant_type_copy): When building a new type variant, we
12384 assume that it is equivalent to the original type.
12385 (build_pointer_type_for_mode): When building a pointer type, also
12386 build a canonical type pointer.
12387 (build_reference_type_for_mode): When building a reference type,
12388 also build a canonical type reference.
12389 (build_index_type): When we can't hash an index type (e.g.,
12390 because its maximum value is negative), the index type requires
12391 structural equality tests.
12392 (build_array_type): Build the canonical form of an array type.
12393 (build_function_type): Function types require structural equality,
12394 because they contain default arguments, attributes, etc.
12395 (build_method_type_directly): Ditto for method types.
