   Comments

   [vm/compiler] AOT bounds check elimination
   
   Rationale:
   With the new induction variable bounds in place, this
   is the first very low hanging fruit. When a loop bound
   matches the array bounds check, it is redundant. This
   removes AOT non-speculative bounds checks for the first
   time. More improvements to follow!
