[Support] Add an enable bit to our DebugCounters
r337748 made us start incrementing DebugCounters all of the time. This
makes tsan unhappy in multithreaded environments.
Since it doesn't make much sense to use DebugCounters with multiple
threads, this patch makes us only count anything if the user passed a
-debug-counter option or if some other piece of code explicitly asks
for it (e.g. the pass in D50031).
The amount of global state here makes writing a unittest for this
behavior somewhat awkward. So, no test is provided.

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.
