Ruben Ayrapetyan 446e8bf989 Replacing 'this_arg' meta opcode with more general 'call site additional information' meta opcode with flags describing the call site features, and, optionally, 'this' argument. 
Introducing opcode_call_flags_t for argument of the new meta opcode, currently with two flags: 'have this argument' and '"direct call to eval" form'.
