Subject: [PATCH] Remove panic in ConsumeCoverageData() when no coverage is
 observed.

A call to ConsumeCoverageData() can observe zero incremental coverage
immediately after a concurrent call to ConsumeCoverageData() unlocks coverageMu
if sync.Mutex.Lock/Unlock are excluded from coverage instrumentation.
