Eli Friedman 7dd2561740 [LoopReroll] Fix reroll root legality checking. ...

The code checked that the first root was an appropriate distance from
the base value, but skipped checking the other roots. This could lead to
rerolling a loop that can't be legally rerolled (at least, not without
rewriting the loop in a non-trivial way).
