V4 IR: Add loop peeling.
By peeling the first iteration off of a loop and putting it in front of
the loop, type inference can deduce more type information for esp. loop
induction variables. To prevent increasing the code size too much, only
the inner-most loops are peeled.
This gives a 10% speed-up on crypto.js.
