[SCEV] Assign LoopPropertiesCache in the move constructor

In a previous change I collapsed two different caches into one.  When
doing that I noticed that ScalarEvolution's move constructor was not
moving those caches.

To keep the previous change simple, I've moved that bugfix into this
separate change.
