All functions in QElapsedTimer are marked Q_DECL_NOTHROW. This code
is often introduced in many places to deal with timeouts and doesn't
need exception handlers. In particular, it's used in QMutex locking.
In addition, mark QDateTime::currentMSecsSinceEpoch as nothrow, as it
can't throw exceptions either and it is needed by the generic
QElapsedTimer.
Q{Date,Time}::current{Date,Time} operate on local time and run into at
least one cancellation point, which we must consider throwing. And
returning a QDateTime allocates memory.
