/* Inserts a fake frame scoped to the 'tea\noop' internal function into the

 * stack active in the executor globals, the fake frame will be added to the
 * top of the stack.
 *
 * Motivation: sometimes it is necessary to emulate code execution during
 * runtime (e.g. a custom opcode handler) or to create an execution context
 * for certain functionality (e.g. throw an exception when there is no active
 * execution context). A fake frame provides an execution context for these
 * cases.
