Title: Add is* accessor support to ClosureExpressionVisitor#getObjectFieldValue...

I note that the documentation for this method reads "is*() is not supported," but I wasn't sure if this was by design or something to be implemented at a later date. For my company, it would be very helpful to have is* methods checked because all of our boolean members use them.
