Previously, when taking a tear-off, a separate Context object was allocated in order to capture receiver. Now, receiver is stored directly in the Closure object in the 'context' field. This saves 1 object allocation per tear-off and makes tear-offs cheaper compared to explicit closures which can share context with other closures.
