Subject: [PATCH] Qt::totally_ordered_wrapper: specialize QTypeInfo

Simple: just inherit the payload type's (QTypeInfoMerger isn't needed,
as the sizeof totally_ordered_wrapper<P> is the same as the sizeof P).

Yes, this means Qt::totally_ordered_wrapper<P> is marked as isPointer,
but that trait is already deprecated.

Found in API-Review.
