-------------------------------------------------------

[~busbey] This is a big change. Maybe too much for a point release on a 1.2? Its all internals
stuff though. Probably better in a 1.3. A 1.3 that has little in it that follows 1.2 might
be the way to go.

> This is general fix for increments (appends, checkAnd*) perf-regression identified in
the parent issue. HBASE-15031 has a narrow fix for branch-1.1 and branch-1.0.
