Alexander Markov a9abc64613 [vm/bytecode] Add context IDs to disambiguate accesses to distinct contexts 
This CL adds context ID operand to AllocateContext, CloneContext,
LoadContextVar and StoreContextVar bytecode instructions.
The context ID will be used to create distinct Slots and disambiguate
accesses to context objects corresponding to different scopes.
