Original Commit Message:

    This adds support for deoptimizing into the JSConstructStub after the
    receiver instantiation but before the actual constructor invocation.
    Such a deoptimization point is needed for cases where instantiation
    might be observed (e.g. when new.target is a proxy) and hence might
    trigger a deopt.

    We use this new deoptimization point for the "after" frame-state the
    inliner attaches to {JSCreate} nodes being inserted when constructor
    calls are being inlined.
