22802 * c-common.c (c_common_nodes_and_builtins): Since variants of

22814 own canonical type.
22815 (build_type_attribute_qual_variant): When building an attribute
22816 variant, its canonical type is the non-attribute variant. However,
22817 if the attributes are target-dependent and they differ, we need to
22818 use structural equality checks for this type.
22819 (build_qualified_type): A qualified type is not equivalent to its
22820 unqualified variant; set the canonical type appropriately.
22821 (build_distinct_type_copy): When building a distinct type from
22822 another type, the new type is its own canonical type.
22823 (build_variant_type_copy): When building a new type variant, we
22824 assume that it is equivalent to the original type.
22825 (build_pointer_type_for_mode): When building a pointer type, also
22826 build a canonical type pointer.
22827 (build_reference_type_for_mode): When building a reference type,
22828 also build a canonical type reference.
22829 (build_index_type): When we can't hash an index type (e.g.,
22830 because its maximum value is negative), the index type requires
22831 structural equality tests.
22832 (build_array_type): Build the canonical form of an array type.
22833 (build_function_type): Function types require structural equality,
22834 because they contain default arguments, attributes, etc.
22835 (build_method_type_directly): Ditto for method types.
