[NO ISSUE][RT] Eliminate Excessive Object Creation in Sort Merge

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Currently, every binary search for frame lookup during
  the sort merge phase results in auto-boxing to an Integer.
  In addition, every call to InnerFrameInfo#compareTo during
  the binary search results another auto-boxing. This change
  eliminates these objects creation by using a MutableInt and
  and using a primitive int comparison while comparing.
