24053 * c-common.c (c_common_nodes_and_builtins): Since variants of

24055 give those variants the name, too.

24065 own canonical type.
24066 (build_type_attribute_qual_variant): When building an attribute
24067 variant, its canonical type is the non-attribute variant. However,
24068 if the attributes are target-dependent and they differ, we need to
24069 use structural equality checks for this type.
24070 (build_qualified_type): A qualified type is not equivalent to its
24071 unqualified variant; set the canonical type appropriately.
24072 (build_distinct_type_copy): When building a distinct type from
24073 another type, the new type is its own canonical type.
24074 (build_variant_type_copy): When building a new type variant, we
24075 assume that it is equivalent to the original type.
24076 (build_pointer_type_for_mode): When building a pointer type, also
24077 build a canonical type pointer.
24078 (build_reference_type_for_mode): When building a reference type,
24079 also build a canonical type reference.
24080 (build_index_type): When we can't hash an index type (e.g.,
24081 because its maximum value is negative), the index type requires
24082 structural equality tests.
24083 (build_array_type): Build the canonical form of an array type.
24084 (build_function_type): Function types require structural equality,
24085 because they contain default arguments, attributes, etc.
24086 (build_method_type_directly): Ditto for method types.
24087 (build_offset_type): Build the canonical offset type.
