Improve argument validation in copyOfRange

Browse Source 
Make copyOfRange implementation non-inline in order not to expose
copyOfRangeToIndexCheck implementation detail.

It will be possible to make the function non-inline itself later without
that JvmName trick, when apiVersion 1.2 support is discontinued.
