lgtm, although I do not fully understand why there is the call to
FindOptimalSplitPos after we find a valid split position.

There are many positions we may split. Before, we were picking the one just
before the first use needing
a register. That may not be optimal, because it may happen the first such use is
in a loop. The optimal
position logic attempts to find an alternative, valid split position, outside of
a loop.
