Alexander Markov 336969538c [vm/bytecode] Revise representation of types, constants and calls in bytecode 
* Type arguments are moved to global object table (and de-duplicated).
* Finalize non-recursive generic types at bytecode generation time.
* Constants are moved to global object table (and de-duplicated).
* ICData creation is avoided for direct calls.
* Interface calls reference target member instead of selector name.

Size of a dilp files: 17868K => 15896K (-11%).
