Daniel Tschinder 10cd6519d8 Fix class inheritance in IE <=10 (T3041) (#3527)
* 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
