Introduce DebugCounter into DCE pass

Authored by zhizhouy on Jul 31 2018, 11:23 AM.



This patch introduces DebugCounter into DCE pass at per-transformation level.

It will provide an option skip first n or stop after n transformations for the whole DCE pass.

This will make debug easier for the pass, also providing chance to do transformation level bisecting.
