Remove unused variable op2. It is redeclared later.

Fix FE_FETCH_* exception check

Only applying this for 7.2, because handling this would be ugly
under the old retval freeing semantics.

Fixed bug #74810

And also did some general cleanup in ZEND_FUNC_GET_ARGS.

Added specialized FE_FETCH_R handler for iteration over array

FE_RESER/FE_FETCH optimisation

VM refactoring, to avoid passing "execute_data" into helper functions that can access it using global register variable.

Moved "Using $this when not in object context" exception code into single VM helper.

Avoid run-time checks performed at compile-time.

Removed unused variable.

ZVAL_COPY_UNREF() micro-optimization

Update opcode description

Fixed support for C compilers that don't support global register variables.

Added ZEND_FUNC_NUM_ARGS, ZEND_FUNC_GET_ARGS instructions, to implement corresponding builtin functions.
Special optimisation for "array_slice(INT, func_get_args())" pattern.

Extend ZEND_SEND_ARRAY to eliminate array_slice() call for "call_user_func_array(_, array_slice(_, LONG, _))" pattern.

Added ZEND_GET_CLASS, ZEMD_GET_CALLED_CLASS, ZEND_GET_TYPE instructions, to implement corresponding builtin functions.

Added ZEND_COUNT instruction, to implement corresponding builtin.

Fixed ZEND_IN_ARRAY related issues

Added ZEND_IN_ARRAY instruction, implementing optimized in_array() builtin function, through hash lookup in flipped array

Fixed segfult in JIT (emalloc may trigger memory limitation)

Zend/tests/bug68412.phpt

Remove unused opcode handlers

Avoid useless checks

Implemented HYBRID VM instruction dispatch method that takes advantages of both CALL and GOTO VMs.

Initialize retval in INCLUDE_OR_EVAL

In case the eval'd code throws.

Implement jumptable optimization
