This is a continuation of the previous five commits. A first big step into the direction of no longer having to pass a realm (or currently, a global object) trough layers upon layers of AOs! Unlike the create() APIs we can safely assume that this is only ever called when a running execution context and therefore current realm exists. If not, you can always manually allocate the Error and put it in a Completion :^) In the spec, throw exceptions implicitly use the current realm's intrinsics as well: https://tc39.es/ecma262/#sec-throw-an-exception
