Summary:
This patch will print out {Counter, Skip, StopAfter} info of all passes which have DebugCounter set at destruction.
It can be used to monitor how many times does certain transformation happen in a pass, and also help check if -debug-counter option is set correctly.
Please refer to this [[ http://lists.llvm.org/pipermail/llvm-dev/2018-July/124722.html | thread ]] for motivation.
