Pavel Kirpichenkov 07ca355af8 [NI] Fix smartcasts for conventional contains in when

Call argument for conventional `contains` after expanding `in` may come from a `when` subject during its branch analysis.
In this case data flow info from a previous when branch was not considered,
because data flow info for subject had been used instead of data flow before argument.
Use of the latter one for the conventional `contains` solves the issue.

The old FE uses `isExternal` property of value arguments to skip smartcast reporting on `when` subject,
if they come from branches. To prevent undesired smartcasts on `when` subject after branch analysis in the new FE,
`isExternal` arguments are skipped in diagnostic reporter and during recorded type update.

Also, the new FE interprets `isExternal` completely differently from the old FE.
In the old FE this property is used exclusively by `when` with subject.
In the new FE it is also used for parially resolved calls, lambda return arguments and receivers.
This may be preventing the use of data flow info before argument in the first place, but this assumption requires additional investigation.

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.
