Alexander Markov 62d154f6a3 [vm/bytecode] Record null-initialized fields in bytecode 
If a field is initialized with null (either explicitly or implicitly),
field store can be omitted in bytecode. In such case, bytecode should
still convey the information about this initialization to VM for
field guards to work correctly.
