10205 * c-common.c (c_common_nodes_and_builtins): Since variants of

10217 own canonical type.
10218 (build_type_attribute_qual_variant): When building an attribute
10219 variant, its canonical type is the non-attribute variant. However,
10220 if the attributes are target-dependent and they differ, we need to
10221 use structural equality checks for this type.
10222 (build_qualified_type): A qualified type is not equivalent to its
10223 unqualified variant; set the canonical type appropriately.
10224 (build_distinct_type_copy): When building a distinct type from
10225 another type, the new type is its own canonical type.
10226 (build_variant_type_copy): When building a new type variant, we
10227 assume that it is equivalent to the original type.
10228 (build_pointer_type_for_mode): When building a pointer type, also
10229 build a canonical type pointer.
10230 (build_reference_type_for_mode): When building a reference type,
10231 also build a canonical type reference.
10232 (build_index_type): When we can't hash an index type (e.g.,
10233 because its maximum value is negative), the index type requires
10234 structural equality tests.
10235 (build_array_type): Build the canonical form of an array type.
10236 (build_function_type): Function types require structural equality,
10237 because they contain default arguments, attributes, etc.
10238 (build_method_type_directly): Ditto for method types.
