[DebugCounters] Keep track of total counts
This patch makes debug counters keep track of the total number of times we've called `shouldExecute` for each counter, so it's easier to build automated tooling on top of these. A patch to print these counts is coming soon. Patch by Zhizhou Yang! Differential Revision: https://reviews.llvm.org/D49560 llvm-svn: 337748
