LifeMeter->IsFailing()
-- whether the player would fail if a failure check was made right now
bFailedEarlier
-- whether the player was failing at some point
bFailed
-- whether the player actually failed
bFailedEarlier is set even in FailOff, but other than that the two
are identical. Most of the time, use bFailed; in FailOff, the player
should never fail, so bFailedEarlier should be meaningless.
