> Extend QueryVisitor to support multi-term queries

> Currently, QueryVisitor only allows queries to report that they consume a
> fixed set of terms. For multi-term queries, however, they don't know which
> terms in an index they're going to match until rewrite time. Current users
> of this API get round this by using instanceof checks in a `visitLeaf()`
> method, but this is clunky and does not adapt well to user-defined queries.
> We should extend QueryVisitor so that queries can report that they consume a
> class of terms matching an automaton, in addition to individual terms.
