Details

During jwplayer.flash.swf's startup, we call forwardValueOf more than 3000 times and forwardToString almost 2400 times. Given that they'll be called from lots of different places, probably not a single one of these calls is inlined, meaning we take the hit of the indirection every single time. I think what we can do is only install them on the prototype of ASObject or, even better, only on classes that actually define a public valueOf or toString method.
The whole forwarder mechanism doesn't exist anymore.
