29969 * c-common.c (c_common_nodes_and_builtins): Since variants of
29970 void_type_node get built before it is given a name, we need to
29971 give those variants the name, too.

29978 alignment of a type for which we're building an array, we end up
29979 guessing wrong, so make the type require structural equality.
29980 * tree.c (make_node_stat): When we build a new type, it is its
29981 own canonical type.
29982 (build_type_attribute_qual_variant): When building an attribute
29983 variant, its canonical type is the non-attribute variant. However,
29984 if the attributes are target-dependent and they differ, we need to
29985 use structural equality checks for this type.
29986 (build_qualified_type): A qualified type is not equivalent to its
29987 unqualified variant; set the canonical type appropriately.
29988 (build_distinct_type_copy): When building a distinct type from
29989 another type, the new type is its own canonical type.
29990 (build_variant_type_copy): When building a new type variant, we
29991 assume that it is equivalent to the original type.
29992 (build_pointer_type_for_mode): When building a pointer type, also
29993 build a canonical type pointer.
29994 (build_reference_type_for_mode): When building a reference type,
29995 also build a canonical type reference.
29996 (build_index_type): When we can't hash an index type (e.g.,
29997 because its maximum value is negative), the index type requires
29998 structural equality tests.
29999 (build_array_type): Build the canonical form of an array type.
30000 (build_function_type): Function types require structural equality,
30001 because they contain default arguments, attributes, etc.
30002 (build_method_type_directly): Ditto for method types.
30003 (build_offset_type): Build the canonical offset type.
