summary:     Bug 755186 - rm JS_NewGlobalObject (r=jorendorff)
The test-case repros before bug 755186 with s/same-compartment/new-compartment/.  (After bug 755186, all newGlobal() create a new compartment -- the argument is now ignored.)

Steve: I'm guessing this assert is innocuous, is that right?
No longer blocks: 755186
var otherGlobal = newGlobal("new-compartment");
var proxy = otherGlobal.Proxy.create({}, {});
Int8Array.set(proxy);

Attached patch rmSplinter Review
The assert is overzealous.  I'm not sure if the property it is trying to ensure is even something we generally want anymore.  Waldo will actually be overhauling this area pretty soon.
