  Changed paths:
    M clang/lib/DirectoryWatcher/windows/DirectoryWatcher-windows.cpp

  Log Message:
  -----------
  DirectoryWatcher: close a possible window of race on Windows

The initial scan occurring before the watcher is ready allows a race
condition where a change occurs before the initial scan completes.
Ensure that we wait for the watcher to begin executing the initial scan.

Addresses some feedback from Adrian McCarthy in post-commit review.
