1275312 - Consider adding a public GetPrototypeFromConstructor API

Status: NEW

(Core :: JavaScript Engine, defect)

Description

[Boris Zbarsky [:bzbarsky]]

It could look something like:

  JS::GetPrototypeFromConstructor(JSContext *cx,
                                  JSObject* ctor, 
                                  JSProtoKey key);

And yes, I know we already have a js::GetPrototypeFromConstructor with different semantics...

JS_NewObjectForConstructor() should be updated instead.

It currently (at least on JSAPI45) doesn't behave correctly when the class in subclassed.
