Description

Spinoff/blocker for LUCENE-5879.

It seems like PrefixQuery should "simply" be an AutomatonQuery rather than specializing its own TermsEnum ... with maybe some performance improvements to ByteRunAutomaton.run to short-circuit once it's in a "sink state", AutomatonTermsEnum could be just as fast as PrefixTermsEnum.

If we can do this it will make LUCENE-5879 simpler.
