28996 (build_type_attribute_qual_variant): When building an attribute
28997 variant, its canonical type is the non-attribute variant. However,
28998 if the attributes are target-dependent and they differ, we need to
28999 use structural equality checks for this type.
29000 (build_qualified_type): A qualified type is not equivalent to its
29001 unqualified variant; set the canonical type appropriately.
29002 (build_distinct_type_copy): When building a distinct type from
29003 another type, the new type is its own canonical type.
29004 (build_variant_type_copy): When building a new type variant, we
29005 assume that it is equivalent to the original type.
29006 (build_pointer_type_for_mode): When building a pointer type, also
29007 build a canonical type pointer.
29008 (build_reference_type_for_mode): When building a reference type,
29009 also build a canonical type reference.
29010 (build_index_type): When we can't hash an index type (e.g.,
29011 because its maximum value is negative), the index type requires
29012 structural equality tests.
29013 (build_array_type): Build the canonical form of an array type.
29014 (build_function_type): Function types require structural equality,
29015 because they contain default arguments, attributes, etc.
29016 (build_method_type_directly): Ditto for method types.
29017 (build_offset_type): Build the canonical offset type.
