- Map generated explicit Unit returns to the closing brace of
the original body
- Name the continuation parameter as `$completion` to match the JVM BE,
and generate debug info for it (so that it appears in the 'names'
array in sourcemaps)
- Don't generate debug info for coroutine instantiation ceremony
(so that the user doesn't need to step in many times to get where they
want)

its meaning, specifically it will add kotlin stdlib to test's classpath.
