hg: mlvm/mlvm/jdk: added tests and CoroutineLocals

[Charles Oliver Nutter]

Exciting :) Once you get it in, perhaps you can release the changes
you made to JRuby. I have no problem shipping a reflectively-loaded
version of Fiber that uses JVM coroutines! (and I'd like to do the
same for 1.8 mode Enumerator, which also requires coroutine support)
