Since an immediate invocation is a full expression itself - it requires
an additional ExprWithCleanups node, but it can participate to a bigger
full expression which actually requires cleanups to be run after.

Thanks @ilya-biryukov for helping reducing the reproducer and confirming
that the analysis is correct.
