[PATCH] [MIScheduler] Slightly better handling of constrainLocalCopy when both source and dest are local

[Michael Kuperstein]

Thanks a lot, Andrew!

As I wrote on the PR, I don't fully understand the surrounding code.
One of the constraints is that the "global" LI has at least one segment after the one that contains the start of the "local" LI. So a "global" LI with exactly one segment will never satisfy it, right? That's the case that I was trying to kill.

Anyway, if you're sure that treating the dest as the "global" works in all cases, I'm perfectly ok with that as well. :-)
