Hi,

some minor cleanups and enhancements in and around java.lang.ClassLoader
which add up to a small startup improvement:

- Remove use of Vector/Hashtable from ClassLoader, along with a few
   other improvements/modernizations.
- Refactor ClassLoader::sys_paths/user_paths so that they're initialized
lazily but also published safely

Bug:    https://bugs.openjdk.java.net/browse/JDK-8236075

Testing: tier1-3
