[Cownie, James H]

Phabricator doesn't seem to have openmp-dev as an option, so I'm copying here by hand.

Subject: [PATCH] D11759: Tidy statistics collection

jcownie created this revision.
jcownie added reviewers: hfinkel, jlpeyton, openmp-commits.

This removes some statistics counters and timers which were not used,
adds new counters and timers for some language features that were not
monitored previously and separates the counters and timers into those
which are of interest for investigating user code and those which are
only of interest to the developer of the runtime itself. 
The runtime developer statistics are now ony collected if the
additional #define KMP_DEVELOPER_STATS is set.
 
Additional user statistics which are now collected include
   Count of nested parallelism (omp parallel inside a parallel
   region)
   Count of omp distribute occurrences
   Count of omp teams occurrences
   Counts of task related statistics (taskyield, task execution, task
   cancellation, task steal)
   Values passed to omp_set_numtheads

None of this affects code compiled without stats gathering enabled,
which is the normal library build mode.
