* perf: improve actor storage performance This minimizes the amount of marshal & unmarshal calls being made when using `actor.WithStorage`. I used the test `TestTipSetWeightDeep` as benchmark and went from `140s` to `61s`. When applying ipfs/go-ipld-cbor#45 the time goes down to `45s`. Warning: this reduces the strictness of the vm memory barrier with the rest of filecoin, but we accept this as a tradeof for now, to improve performance. Ref #979

@dignifiedquire this may not help but could you test if you have time? The internal benchmarks don't seem to capture real-world gc issues very well.
