The change in the run configuration "Binary compatibility tests, overwrite results"
is to prevent incremental compilation of these artifacts.
During the incremental compilation only the declarations in the files being
recompiled are dumped to declarations.json.
This results in incomplete dump and affects the public declarations dump.
This clean step enforces stdlib and reflect libraries to be fully recompiled.
This step can be removed as soon as we do not need declarations.json to dump public API.
