[vm/aot/tfa] Infer int type, devirtualize dynamic calls This change improves type flow analysis to infer int types, in addition to concrete classes (int type is abstract and has 2 concrete subclasses, _Smi and _Mint). Also, this CL enables devirtualization of dynamic calls (previously, only calls with known interface target were devirtualized).
