Cause: loadSubScript calls EvaluateUCScript with a scope chain that has a parent (i.e., is not the global object). Our optimizations for globals assume that the initial scope chain and the global are the same, so those optimizations are not valid in this case.

Patch deoptimizes globals if the initial scope chain is not the global.
