Fixed bug #33257 (array_splice() inconsistent when passed function instead of variable)

Removed EX(fbc_constructor) (it is no longer needed)

Allowed return by refrence from internal functions

Fixed bug #33318 (throw 1; results in Invalid opcode 108/1/8)

Compilation warnings

ZEND_UNSET_DIM_OBJ is splitted to ZEND_UNSET_DIM and ZEND_UNSET_OBJ.

USER_OPCODE API is improvet.
Implemented ability to dispatch from user handler to internal handler of another opcode.

Removed old executor

Specializer optimization

Fix so that extensions like xdebug, can overload opcodes in all execution modes including goto/switch

Merge three opcodes (ZEND_NEW, ZEND_JMP_NO_CTOR, ZEND_INIT_CTOR) into one (ZEND_NEW). There was no real reason for this anymore and API should be changed before 5.1

Fixed exception handling in getIterator() callback (bugs #26229 & #30725)

- MF44: Problems with user defined error handler and references

- Regenerate VM files and add warning about regeneration

Fixed bug #32993 (implemented Iterator function current() don't throw exception)

Fixed memory allocation bugs related to magic object handlers (__get(), __set(),
...)

Fixed bug #22836 (returning reference to uninitialized variable)

Fixed bug #30707 (Segmentation fault on exception in method)

Fixed bug #30162 (Catching exception in constructor couses lose of $this)

Fixed bug #32833 (Invalid opcode)

Fixed bug #32674 (exception in iterator causes crash)

Fixed bug #30889 (Conflict between __get/__set and ++ operator)

Fix certain operations to stop relying on presence of read_property and
write_property handlers. They may be NULL'ed out by certain objects
pretending to be pure arrays, for example. Do check
