OldNativeFunction should catch exceptions thrown from native .impl and rethrow

[cpcallen]

There are a small but non-zero number of native functions that we implement using OldNativeFunction (via createNativeFunction), including String.prototype.localeCompare that can throw (native) errors when given invalid arguments. This will cause the interpreter to crash.

These should probably ultimately be rewritten as (new) NativeFunctions, but in the interim OldNativeFunction.prototype.call and .construct should catch any native thrown by this.impl.apply(…) and rethrow the corresponding pseudo error generated by applying errorNativeToPseudo.

This is somewhat related to #456.
