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.

1fe2817457 Introduce parser-time optimization that moves function's argument values to registers. 
For functions with the optimization applied:
 - vm puts arguments values immediately to registers without putting them to variables in lexical environment;
 - number of arguments is extracted from corresponding 'reg_var_decl' instruction's argument;
 - for functions that also don't have local variables, lexical environments are not created.
