RFR: 8279653: compiler/codecache/stress/OverloadCompileQueueTest.java failing in loom repo

[Coleen Phillimore]

I fixed the test to disable compiling Thread.sleep() and all the methods it seems to call, and this makes the test pass.  I don't know if there's a better way to disable compilation like this that would be less fragile (ie if Thread.sleep() calls something new in the future).  See bug comments for details.  @rickard  do you know?  Thanks!
