This fixes a corner-case in the above predicate that was introduced to
allow fully disabling optimization using %NeverOptimizeFunction. This
property of a function is a transient property (i.e. changes over time),
whereas {UseTurboFan} is designed to be a static property (i.e. gives
same answer over time). Violating this led to cases where functions got
optimization disabled for other reasons would suddenly be baselined.
The correct place to check transient properties is when optimization is
requested.
