Fix for issue 603. Revision r3484 removed the property name from the call stack for call ICs. When a non-function was called via a call IC and Function.prototype.call, an extra value was left on the stack that the caller could not know to clean up. Fix is to change the JS builtin used for calling non-functions. It now gets the callee as receiver, rather than iterating stack frames and finding it on the expression stack of its JS caller.
