Description
Lucene does all searching/filtering per-segment, today, but there are a number of tests that directly invoke Scorer.scorer or Filter.getDocIdSet on a composite reader.

Attached patch.
Only a few query impls were affected, but many tests were directly passing composite readers to the low level API. I added a new helper class SlowMultiReaderWrapper that one can use to wrap an existing composite reader to make it [inefficiently] pretend it's an atomic reader.
