1. JIT: Extract all side effects of the index in optRemoveRangeCheck …

   optRemoveRangeCheck extracts only GTF_ASG from the bounds check. If the
   BOUNDS_CHECK is complex, that results in silently dropping side effects
   on the floor (see the example case).
   
   The ideal fix is that we should always extract all side effects from the
   index and length operands, however this has large regressions because
   the length typically has an ARR_LENGTH that we then extract. This PR
   instead has a surgical fix for the problem case that can be backported
   to .NET 8. It extracts all side effects from the index, but keeps
   extracting only GTF_ASG from the length to get around the issue
   mentioned above.
   
   Fix #91862
