The case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different

fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.

A test in allocation-site-info.js was beefed up to make sure the state
