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.
