This is a tree-optimization bug for 4.0 and later. I think the problem
is that we don't catch the store motion opportunity at the tree level
because to the tree alias analyses arrays are opaque objects. On RTL
we can distinguish the array members.
If this is the problem, then Dan's sa-branch work should fix it...
Dan?
