Array mapper is bug 27, r750 and r764.

I think maybe at the time there were no array literals in arbitrary 
locations? (I think there didn't used to be early on...?)

Which would make it not quite a superset of the fixed_array_mapper at the 
time it was introduced, though it looks like it is now (except apparently 
its broken, so it isn't...)
