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.

a4e54e736e Support syntax error feedback in parser.
Now, parser correctly finishes parse procedure if syntax of source code is incorrect (syntax correctness is indicated using return value):
 - parser-internal memory management is performed using jsp_mm_alloc / jsp_mm_free;
 - upon detection of incorrect syntax, all parser-allocated memory regions are deallocated using jsp_mm_free_all and parse finishes with corresponding return value.

85f12de139 Introduce parser-specific managed memory allocator with interface jsp_mm_free_all that, upon call, frees all memory allocated with the allocator.
