6712 * c-common.c (c_common_nodes_and_builtins): Since variants of

6725 (build_type_attribute_qual_variant): When building an attribute
6726 variant, its canonical type is the non-attribute variant. However,

6728 use structural equality checks for this type.
6729 (build_qualified_type): A qualified type is not equivalent to its
6730 unqualified variant; set the canonical type appropriately.

6738 also build a canonical type reference.
6739 (build_index_type): When we can't hash an index type (e.g.,
6740 because its maximum value is negative), the index type requires
6741 structural equality tests.
6742 (build_array_type): Build the canonical form of an array type.
6743 (build_function_type): Function types require structural equality,
6744 because they contain default arguments, attributes, etc.
6745 (build_method_type_directly): Ditto for method types.
6746 (build_offset_type): Build the canonical offset type.
6747 (build_complex_type): Build the canonical vector type.
