* [JIT] Switch executor from Simple to Legacy.
This is done for 1.6 only in order to recover performance regressions
caused by the Legacy->Simple switch that was done in 1.5. On master we
still plan to use Simple executor and fix the performance issues in 1.7
without falling back to the Legacy executor.
