24837 (build_type_attribute_qual_variant): When building an attribute
24838 variant, its canonical type is the non-attribute variant. However,
24839 if the attributes are target-dependent and they differ, we need to
24840 use structural equality checks for this type.
24841 (build_qualified_type): A qualified type is not equivalent to its
24842 unqualified variant; set the canonical type appropriately.
24843 (build_distinct_type_copy): When building a distinct type from
24844 another type, the new type is its own canonical type.
24845 (build_variant_type_copy): When building a new type variant, we
24846 assume that it is equivalent to the original type.
24847 (build_pointer_type_for_mode): When building a pointer type, also
24848 build a canonical type pointer.
24849 (build_reference_type_for_mode): When building a reference type,
24850 also build a canonical type reference.
24851 (build_index_type): When we can't hash an index type (e.g.,
24852 because its maximum value is negative), the index type requires
24853 structural equality tests.
24854 (build_array_type): Build the canonical form of an array type.
24855 (build_function_type): Function types require structural equality,
24856 because they contain default arguments, attributes, etc.
24857 (build_method_type_directly): Ditto for method types.
