    Preserve feedback and speculation mode for JSCall · 149e4935
    Nico Hartmann authored
    Changing the target of JSCall nodes (e.g. while lowering higher order calls)
    now preserves feedback and speculation mode to allow further (speculative)
    optimizations. A flag is introduced to mark feedback unrelated to the call
    target after such a transformation. This flag is used to prevent access to
    the feedback without the need to invalidate it.
