optimization/5200: Store Motion is broken

[Steven Bosscher]

Hi,

Nathaneal Nerode asked for confirmation of this PR in early January,
but there was no reply.

Usually that would mean "close it, no feedback for more than three
months".  But this is special because so many people have looked at
it and because Zdenek was working on a store motion rewrite some
time ago.

Can somebody look at it and see if the problem still exists, and change
the status of the PR accordingly (ie. analyzed or closed)?

Thanks,
Steven
