When transpiling JavaScript, TS3.1+ emits `@extends` tags as code. E.g.
/** @extends {SuperClass} */
class SubClass {}
Causes an ES5 emit that references SuperClass:
/**
* @extends {SomeBase}
*/
var SubClass = /** @class */ (function (_super) {
__extends(SubClass, _super);
function SubClass() {
return _super !== null && _super.apply(this, arguments) || this;
}
return SubClass;
}(SomeBase));
Note the literal references to `SomeBase`.
This appears to be an accidental effect of 0f55566cf4. It refactored
`getEffectiveBaseTypeNode` for type checking, but missed an instance
where it is also used for emit logic. This change fixes the problem by
specifically getting the heritage clauses directly off the AST.
