    Original Commit Message:
    
        Since now the IterationBody StackChecks are implicit within JumpLoops,
        we are able to eagerly deopt in them. If we do that, whenever we advance
        to the next bytecode we don't have to advance to the next literal
        bytecode, but instead "advance" in the sense of doing the JumpLoop.
    
        Adding tests that test this advancing for wide and extra wide JumpLoops.
    
        Also, marking JumpLoop as needing source positions since now it has
        the ability of causing an interrupt.
