295590 Helgrind: Assertion 'cvi->nWaiters > 0' failed when cond var being waited upon destroyed
* when cond var is destroyed, in the PRE, report an error if nwaiters > 0.
* when cond_wait succeeds, get the cond var but do not create one in helgrind
(it must exist if cond_wait was done).
Report an error if cond not found (assuming this is caused by a destroy
done while the thread was cond_wait-ing).
* added a test
