AvailVariableAccessNote

An AvailVariableAccessNote is a helper class used during data flow analysis. As it progresses forward through a block's AvailInstructions, it tracks, for a particular variable, the most recent instruction which pushes that variable itself on the stack. It also tracks the most recent instruction which pushes that variable's value on the stack.
