Includes all traps except the following: [[Call]], [[Construct]], [[OwnPropertyKeys]]. An important implication of this commit is that any call to any virtual Object method has the potential to throw an exception. These methods were not checked in this commit -- a future commit will have to protect these various method calls throughout the codebase.
