[GB.FORM.TERMINAL]
* BUG: Fix warning messages.
[GB.JIT]
* BUG: Fix byte, short and boolean pushing and popping routines.
* BUG: Fix string values referencing.
* BUG: Fix optional argument management.
* NEW: Optimization of bits management subroutines.
[GB.QT4]
* BUG: Delay hooks initialization, because now socket notifiers must not be used before creating the event loop.
[GB.QT5]
* BUG: Delay hooks initialization, because now socket notifiers must not be used before creating the event loop.
[INTERPRETER]
* OPT: String routines are now compiled with -O3.
* NEW: Don't display JIT debugging message unless GB_JIT_DEBUG is set to something different from zero.
* NEW: String whose length is greater than 256 now have a growth step of 256 bytes instead of 16.
[GB.JIT]
* NEW: Do many global optimizations as now the class metadata is fully available.
* NEW: Support for optional argument. Still buggy at the moment.
