> I noticed that for the jsc command line tool, the Typed Arrays are actually exposed and can be used. This does not expose the prototype and some API methods, but I guess it's a testament that Typed Arrays really are fully defined internally in JSC itself. See jsc.cpp around line 224:

No, jsc has internally defined a bunch of types that are sufficiently abi compatible for the engine to use them in place of the clusterfuck that is the w3c typed array spec.  They don't have any of the necessary concepts to be used as the basis for the w3c typed arrays, and jsc can only support one or the other of these models.
