in redundant locals elimination.
Since IgnoringCopySourceInterpreter ignores ALOADs and ASTOREs,
the source instruction of ALOAD K in {ALOAD N, ASTORE K, ALOAD K}
sequence is not ASTORE K. In this case we cannot simply replace K
with N, since there can be multiple {ALOAD N, ASTORE K} sequences
in separate branches. After replacement we get different stack
frames.
This change resolves this.
However, in ReturnUnitMethodTransformer we want to ignore copies
of the same GETSTATIC kotlin/Unit.INSTANCE, since we do not mess
with local variables and just replace ASTORE with ARETURN to help
tail-call optimization.

JavaScript Translation
This module performs the translation of Kotlin source code to JavaScript.
There are various Kotlin APIs to JavaScript environments and libraries in the js.libraries project.
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.
