Description
To fix 4917309 (cl) Reduce internal usage of ClassNotFoundExceptions during class-loading, the VM needs to provide an entry point that will find a class from the bootstrap class loader and return null if not found (instead of throwing a ClassNotFoundException).

JVM_FindClassFromBootLoader was added in JDK 7 for 6714758.  We will modify that for this fix.  This will simplify the synchronized pushes of the HotSpot fix and JDK fix.
