Detailed Description

This file implements OnDiskCASLogger.

The logger will write the timestamp and events to a log file using filestream. The logger should be thread-safe and process-safe because each write is small enough to atomically update the file.

The logger can be enabled via LLVM_CAS_LOG environmental variable.
