Fix crashes in Smi equality comparisons: Smi equality instruction may have null as inputs. Null is treated specially in equality and therefore does not enter the ICdata, type feedback does not know about null being encountered.
TODO: fix excessive deoptimziation due to one of the inputs not being Smi.
(Crash was reproduced running test suite with optimization counter threshold 5)

Make event renames optional, not mandatory.

That should lead to less frequent build breaks.
