Avoid live range references in opcodes

Don't store the live range of the freed variable for FREE_ON_RETURN

unlikely code

Avoid live range references in opcodes

Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.

Moved "zval.u2.cache_slot" into free room of "zend_op"

Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and

Avoid repeatable ARG_SHOULD_BE_SENT_BY_REF() checks in FETCH_*FUNC_ARG and following SEND_VAR_EX. Perform the check once in a new CHECK_FUNC_ARG opcode and reuse in the following FETCH_*FUNC_ARG and SEND_FUNC_ARG (SEND_VAR_EX replacement).

Changed CATCH instruction format (extended_value moved into op2, op2 into result, result into extended_value)

Changed FETCH_CONSTANT instruction format (extended_value moved into op1)

Changed FETCH_CLASS instruction format (extended_value moved into op1)

Use fastcall calling convention

Implement list() reference assignments

Support list() reference assignments of the form:

list(&$a, list(&$b, $c)) = $d;

TYPE_CHECK instruction changed. Now it keeps in extended_value a type mask.
This makes check for "boolean" cheaper and allows check combination e.g. (is_string($a) || is_null($a))

Separate ISSET_ISEMPTY_CV/UNSET_CV from ISSET_ISEMPTY_VAR/UNSET_VAR

Removed vim mode lines. zend_vm_opcodes.h loses these lines after regeneration. Lines in zend_vm_def.h lead to insertion inthe middle of zend_vm_execute.h.

further sync for vim mode lines

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.

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.

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

Switch to HYBRID VM

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

Implement jumptable optimization

Update copyright headers to 2017

Fixed bug #71539 (Memory error on $arr[$a] =& $arr[$b] if RHS rehashes)
