Method incrementSampleCounter

src/threadLocalData.h:19–26

Increment the thread-local sample counter. See the `asprof_thread_local_data` docs. This function *is* async-signal safe, and therefore will not initialize the thread-local storage by itself, but will rather do nothing if it's not initialized already. This works fine with the `sample_counter` API since only changes in `sample_counter` matter.
