optimizing: NullCheck elimination How it works: - run a type analysis to propagate null information on instructions - during the last instruction simplifier remove null checks for which the input is known to be not null The current type analysis is actually a nullability analysis but it will be reused in follow up CLs to propagate type information: so it keeps the more convenient name.
