Add support for 'static' fields in multicore gc version w/o tasks. Now we can have static fields and access static fields/methods with Class name. Static blocks are also supported but with very simple invocation solution. All the static blocks are executed right before executing the main method and are executed in random order. The initialization for the static field is not supported yet.
