The standard way of loading resources with built-ins metadata from the
current class loader no longer works in the modular mode on Java 9
because the current class loader is for module 'kotlin.reflect', but the
metadata is located in the module 'kotlin.stdlib'. On Java 9, we now use
the class loader of 'kotlin.stdlib' to load these resources.
#KT-21266 Fixed
Also report the "named does not read unnamed" error, which was not
possible previously because we wouldn't be able to read anything from
kotlin-stdlib (because it was added to the unnamed module by default)
