Alexander Markov a8155f25fc [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).

No measurable impact on Flutter gallery build time in release mode.
