Anton Bannykh d6fcde7316 JS_IR: fix typecheck corner case

Consider `fun <E : I> foo(a: Any?) = a as? E`, where I is an interface.
This check used to fail, because the `a == null` was missing, and
the `isInterface` stdlib method crashes if the first argument
is null. This change adds the null check.

Also this change prettifies the instance check in case of type parameter
left operand.

JavaScript Translation

This module performs the translation of Kotlin source code to JavaScript.

There are various Kotlin APIs to JavaScript environments in the standard library.

Compiling the Kotlin Standard Library for JavaScript

The Kotlin Standard Library for JS is built with gradle, see the corresponding module's ReadMe.

Reusing JVM based test cases in JavaScript

Any Kotlin test cases using the org.junit.Test annotation and the kotlin.test package, such as this test case are automatically converted to JavaScript using QUnit.

This allows the test cases to be run directly in a web page in any web browser.

Using the Kotlin Library in JavaScript

There is a simple sample which shows how to use the Kotlin Standard Library from inside JavaScript in a web page.
