Bogus assert (and recently added).  We can't rejoin from a call whose rejoin state is REJOIN_NONE, so asserted that we never marked a frame as having needing this rejoin due to recompilation activity within such a call.  If the recompilation is followed by (or a result of) throwing an exception, though, we won't be rejoining from the call and the written REJOIN_NONE will not be used.
