[2/2] systemml git commit: [SYSTEMML-2340] Fix indexing hop size
reset on negative reconciliation
[SYSTEMML-2340] Fix indexing hop size reset on negative reconciliation
This patch fixes a loop size propagation issue that combined with other
rewrites can cause crashes and incorrect results. Specifically, the
right indexing hop did not properly allow for size resets as required
for correct reset passes on negative reconciliation after loops.
Furthermore, this patch also adds various tests to ensure this behavior
is preserved for future modifications.
