TM: we try to overflow guard loads
Do I really need to explain why thats a really bad idea?
LIR_ov checks for an arithmetic overflow. If we peephole optimized away the arithmetic op, we check the overflow flag in the processor and it might be set to god knows what. This is a performance bug. No correctness implications.

make sure the nanojit parts are checked into the right repo.
yeah, thanks for the reminder
The addition of addxovi/subxovi/mulxovi made it impossible for this problem to occur.
