Eliminate redundant array bound checks (checks already performed earlier in the DT). · 93113da5

mmassi@chromium.org authored Apr 25, 2012

As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.
