50d124bfc3 Parser optimizations. 
- parser is now non-recursive (i.e. parse function is not called recursively in any case);
 - byte-code is now more compact:
    - constants are now not immediately dumped upon occurence, but later - where necessary;
    - assignments are combined with unary / binary operations;
    - binary operations are encoded more compactly in many cases;
 - byte-code arrays are now allocated separately for each scope (so, GC of the scopes now becomes possible);
 - byte-code is dumped directly into corresponding byte-code arrays:
   - linked lists of op_meta are not now used for main code of a scope.

ed4ff8e5bb Introducing a function object's flag indicating whether Arguments object should be instantiated upon call of the function. 
The Arguments object is supposed to be unnecessary if function's code:
  - doesn't reference 'arguments' identifier;
  - doesn't reference 'eval' identifier (so, it doesn't perform direct call to eval).
