Fixed memory leak because of incorrect 'if ();' optimization

Cleanup (updated comments about optimization of comparison with IS_NULL)

Use ZSTR_ API to access zend_string elements (this is just renaming without semantick changes).

Don't evaluate invalid constant expressions.

Fix rope memory leaks upon exception

Remove ZEND_BRK/ZEND_CONT from VM

These are no longer used at run-time now, only temporarily during
compilation.

Merged FE_FETCH_R[W] with the following ASSIGN[_REF] when assigne to CV.

Removed deprecated conditions

Fixed bug #69549 (Memory leak with opcache.optimization_level=0xFFFFFFFF)

Refactored using specialized opcodes

Removed deprecated code

Reverted part committed by mistake

Optimized strings concatenation.
ZEND_ADD_STRING/VAR/CHAR are replaced with ZEND_ROPE_INTI, ZEND_ROPE_ADD, ZEND_ROPE_END.
Instead of reallocation and copying string on each ZEND_ADD_STRING/VA

Optimized strings concatenation.
ZEND_ADD_STRING/VAR/CHAR are replaced with ZEND_ROPE_INTI, ZEND_ROPE_ADD, ZEND_ROPE_END.
Instead of reallocation and copying string on each ZEND_ADD_STRING/VAR/CAHR, collect all the strings and then allocate and construct the resulting string once.

Fixed optimization patterns

Optimize zend_string_realloc() add more specialized versions zend_string_extend() and zend_string_truncate()

Use fastcall calling convention for most critical ZE subsystems.

Change "foreach" statement behavior (this is just a PoC yet)

- "foreach by value" don't relay on internal array/object pointer and doesnt perform array duplication. It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy.

- it makes no difference if array given to "foreach by value" is reference itself

- "foreach by reference" still use internal array/object pointer and should work similar to PHP-5. (This id not completely implemented)
