30799 * c-common.c (c_common_nodes_and_builtins): Since variants of

30812 (build_type_attribute_qual_variant): When building an attribute
30813 variant, its canonical type is the non-attribute variant. However,
30814 if the attributes are target-dependent and they differ, we need to
30815 use structural equality checks for this type.
30816 (build_qualified_type): A qualified type is not equivalent to its
30817 unqualified variant; set the canonical type appropriately.
30818 (build_distinct_type_copy): When building a distinct type from
30819 another type, the new type is its own canonical type.
30820 (build_variant_type_copy): When building a new type variant, we
30821 assume that it is equivalent to the original type.
30822 (build_pointer_type_for_mode): When building a pointer type, also
30823 build a canonical type pointer.
30824 (build_reference_type_for_mode): When building a reference type,
30825 also build a canonical type reference.
30826 (build_index_type): When we can't hash an index type (e.g.,
30827 because its maximum value is negative), the index type requires
30828 structural equality tests.
30829 (build_array_type): Build the canonical form of an array type.
30830 (build_function_type): Function types require structural equality,
30831 because they contain default arguments, attributes, etc.
30832 (build_method_type_directly): Ditto for method types.
