Andrew Kryczka 215076ef06 Fix TSAN: avoid arena mode with range deletions
Summary:
The range deletion meta-block iterators weren't getting cleaned up properly since they don't support arena allocation. I didn't implement arena support since, in the general case, each iterator is used only once and separately from all other iterators, so there should be no benefit to data locality.

Anyways, this diff fixes up #2370 by treating range deletion iterators as non-arena-allocated.
