6864 after target reinitialization.

31377 * c-common.c (c_common_nodes_and_builtins): Since variants of

31389 own canonical type.
31390 (build_type_attribute_qual_variant): When building an attribute
31391 variant, its canonical type is the non-attribute variant. However,
31392 if the attributes are target-dependent and they differ, we need to
31393 use structural equality checks for this type.
31394 (build_qualified_type): A qualified type is not equivalent to its
31395 unqualified variant; set the canonical type appropriately.
31396 (build_distinct_type_copy): When building a distinct type from
31397 another type, the new type is its own canonical type.
31398 (build_variant_type_copy): When building a new type variant, we
31399 assume that it is equivalent to the original type.
31400 (build_pointer_type_for_mode): When building a pointer type, also
31401 build a canonical type pointer.
31402 (build_reference_type_for_mode): When building a reference type,
31403 also build a canonical type reference.
31404 (build_index_type): When we can't hash an index type (e.g.,
31405 because its maximum value is negative), the index type requires
31406 structural equality tests.
31407 (build_array_type): Build the canonical form of an array type.
31408 (build_function_type): Function types require structural equality,
31409 because they contain default arguments, attributes, etc.
31410 (build_method_type_directly): Ditto for method types.
31411 (build_offset_type): Build the canonical offset type.
31412 (build_complex_type): Build the canonical vector type.
