 I don't think this is an interesting case for optimization: its not
 worth it to slowdown the rest of the allocations for such a marginal
 case. Maybe we could do something in the moving gc to just have one
 instance but even then it's not clear this has any significance in the
 real world.

+Currently we do this optimization manually in case of
+mcs. Many 0-sized arrays have static field -> static ctor
+is generated. And it saved MBs of memory, I think it
+would be nice to have this in runtime to save developer time.
+Or try to search for [0]; in our corlib to see how many
+times it is used.
