5781 * c-common.c (c_common_nodes_and_builtins): Since variants of

5794 (build_type_attribute_qual_variant): When building an attribute
5795 variant, its canonical type is the non-attribute variant. However,

5797 use structural equality checks for this type.
5798 (build_qualified_type): A qualified type is not equivalent to its
5799 unqualified variant; set the canonical type appropriately.
5800 (build_distinct_type_copy): When building a distinct type from
5801 another type, the new type is its own canonical type.

5807 also build a canonical type reference.
5808 (build_index_type): When we can't hash an index type (e.g.,
5809 because its maximum value is negative), the index type requires
5810 structural equality tests.
5811 (build_array_type): Build the canonical form of an array type.
5812 (build_function_type): Function types require structural equality,
5813 because they contain default arguments, attributes, etc.
5814 (build_method_type_directly): Ditto for method types.
5815 (build_offset_type): Build the canonical offset type.
5816 (build_complex_type): Build the canonical vector type.
