This prevents moving a single binding from the LHSvariable of the assignment to another variable during theassignment process.- If a complex assignment tries to update a binding that already hasits bit set then, the value of the binding is shallow-duplicatedbefore proceeding. This ensures that the structure involved in theoriginal complex assignment will not be mutated by further R levelassignments during the original assignment process.For now, no attempt is made to unset the bit if the end of anassignment is not reached because of a jump. This may result in someunnecessary duplications. This could be prevented by maintaining astack of pending assignments to resent the bits on jump, but thatseems like overkill.It might also be useful to use this bit to communicate to functionswhen they are used in a getter/setter context.The bit used is bit 11 in the 'gp' field.
