Simple patch, I just check abort when we merge each DV field.
> Merging of doc values, norms is not abortable

>
> When you call IW.rollback, IW asks all running merges to abort, and the
> merges should periodically check their abort flags (it's a "cooperative"
> mechanism, like thread interrupting in Java).
> In 5.x/trunk we have a nice clean solution where the Directory checks the
> abort bit during writes, so the codec doesn't have to bother with this.
> But in 4.x, we have to call MergeState.checkAbort.work, and I noticed that
> neither DVs nor norms call this.
> Typically this is not a problem since merging DVs and norms is usually fast,
> but for a very large merge / very many DVs and norm'd fields, it could take
> non-trivial time to merge.
