An array of boolean values representing the current execution status of the
program. This allows the state to track nested conditional branches.
The OP_IF and OP_NOTIF operations push a new boolean onto the
controlStack, OP_ELSE flips the top boolean, and OP_ENDIF removes
the top boolean from the controlStack.
Other instructions are only evaluated if controlStack contains no
false items.
