* Fix class inheritance in IE9 & IE10 (T3041) Internet Explorer 9&10 do not support __proto__ at all, don't have Object.setPrototypeOf(), but have Object.getPrototypeOf(). Because of this setting the prototype is not possible, which makes the babelHelpers.inherits() function to set __proto__ although not supported. Afterwards Object.getPrototypeOf() is used, but this one is not respecting the "custom" property __proto__ that we set. The solution is to check for __proto__ first and afterwards fallback to Object.getPrototypeOf(). * Do the same logic in babel-helper-replace-supers * Fix tests * Extract creation of prototype nodes to small helper
