- render the whole line where the error/warning points to, if any, and another
line with '^', like other compilers do
- lowercase diagnostic severity
- decapitalize the message if it doesn't start with a proper name
Reflection interfaces (interfaces in kotlin.reflect.* in core/builtins/) are
now fully considered as built-ins and can be accessed via KotlinBuiltIns. This
increases runtime size by ~20kb, but only because KotlinBuiltIns is static and
is therefore constructed only via resource loading from the compiler classpath
at the moment. As soon as it's possible to inject KotlinBuiltIns to the
particular resolution process, the metadata on JVM will be loaded via standard
annotation mechanism (kotlin.jvm.internal.KotlinClass/KotlinPackage) and wasted
runtime space will be reclaimed
