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.

4d2ad40475 Remove var_decls_count field from scopes_tree header; getting "var_decl"s count using linked_list_get_length instead.

a00079e8ff Reduce number of operand type handling conditional blocks in byte-code dumper, by extracting them to several separate routines that can be used for most cases, remove getop_* routines from vm.

91aecc3bd0 Introduce parser scope types, add scope flags, indicating whether scope contains a function declaration, a 'try' statement, 'with' statement or 'delete' operator.

bd9d1d4afd Improve allocation of memory for byte-code array and literal identifiers hash table.
- literal identifiers hash table and byte-code array are now allocated in one heap block instead of four blocks;
 - memory regions with the hash tables and arrays are now linked into linked list using headers at start of the regions instead of using array_list.
