; FIXME: AAValueSimplify preserves the context but simplifies to a value in the other function, I think.
; Either way, as we settle on the new AAValueSimplifyReturned scheme that replaces AAReturnedValues
; we need to look into this again. For the purpose of making some progress we take this regression
; for now, call site contexts are not on by default anyway (yet).
