QWinEventNotifier: reinterpret 'int signaledCount' as a 'bool signaled'
In fact, this variable can take only two values: 0 and 1. By
interpreting its value as boolean, we can use relaxed store operations
instead of atomic increments. This is safe, because it's guarded by
'activateEventNotifiersPosted' variable, which already provides a
release/acquire semantic.
