With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

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.
