* kotlin-experimental.js has been already merged into kotlin.js
* change library name to kotlin in kotlin-experimental.meta.js in order to produce correct require calls
* concatenate kotlin-experimental.meta.js with kotlin.meta.js
* suppress multiple module declaration warning for such use case
A difference is not obvious when two sets are compared:
there might be just one different element, but
sets would be printed in one line in iteration order
(which is non-fixed for hashsets).
Also the properties:
EXPECTED_JS_FILES_IN_OUTPUT_FOR_STDLIB_ONLY,
EXPECTED_JS_FILES_IN_OUTPUT_FOR_MODULE_STDLIB_ONLY,
EXPECTED_JS_FILES_IN_OUTPUT_NO_COPY,
EXPECTED_JS_FILES_IN_OUTPUT_WITH_ADDITIONAL_LIB_AND_DEFAULT_DIR,
EXPECTED_JS_FILES_IN_OUTPUT_WITH_ADDITIONAL_LIB_AND_CUSTOM_DIR
are hard to distinguish in code and are not convenient to edit.
