Provide a way of checking code coverage

I'd like to check that testing covers all my code.

To avoid a check on every instruction dispatch the best thing to do is to use a TRACE instruction at the beginning of each basic block. There are two ways to get it there.

1. As an option to jmp-compile which changes emitted code
2. Save the original instruction in a lookaside and execute it after TRACE accounting. This would make jmp code larger and ideally needs a goto to the top of the dispatch switch, but java doesn't have goto.
