BoundVariable class Null safety

A BoundVariable represents a local variable bound to a particular value in a Frame.

If the variable is uninitialized, the value will be the NotInitialized Sentinel.

If the variable is being initialized, the value will be the BeingInitialized Sentinel.

If the variable has been optimized out by the compiler, the value will be the OptimizedOut Sentinel.
