We removed an HDiv by hand which was still used by an HChange. The
solution is letting dead code removal do the cleanup.

Removed a fragile "optimization" (looking through an HChange), too,
this obviously never triggered and is hard to get right given all our
global invariants and state/type/... changes.

The repro is a bit tricky, because you need inlining to make our
representations and types disagree in this case.

The Array constructor has a needless dependency on an input argument
that is a Cell. It uses this to walk through to an AllocationSite.
The dependency hampers future work. Instead, pass the AllocationSite
as input to the Array constructor.
