redo 'jit: change our linking module to be able to handle arbitrary exit addresses'
Initialize linkStatus to false in the ARM JIT cores as well.
If block linking isn't enabled then make sure there isn't a performance hit from getting a block number.
On block unlinking, wipe the address from the valid links.
Fix the arbitrary exits. We have to make sure that the block links are cleared entirely.
