Revert "runtime: split mutex profile clocks"
This reverts commit
8ab131fb1256a4a795c610e145c022e22e2d1567 (CL 586796)
Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.
