86a96f2cf1 Changed meaning of "op2" for ZEND_FREE, ZEND_FE_FREE, ZEND_FAST_CALL, ZEND_FAST_RET. 
Previously it was an instruction number.
Now it's an index in op_array->try_cacth_array[].

eb7be5379d Speed up fetching of class entries for self:: parent:: and static:: 
This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS.

At first, it adds few new opcodes to separate class related behaviour:
	FETCH_STATIC_PROP_R
	FETCH_STATIC_PROP_W
	FETCH_STATIC_PROP_RW
	FETCH_STATIC_PROP_FUNC_ARG
	FETCH_STATIC_PROP_UNSET
	FETCH_STATIC_PROP_IS
	UNSET_STATIC_PROP
	ISSET_ISEMPTY_STATIC_PROP
	FETCH_CLASS_CONSTANT

At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones:
	INIT_STATIC_METHOD_CALL
	NEW
	END_INSTANCEOF

Finaly, opcache optimizer had to be fixed to support new opcodes.

cc3c425af8 Fix bug #70662 
This replaces add_new with update for the RW case. This should not
be problematic for performance, as this branch throws a notice.

Alternatively add_new could also be replaced with add. I went with
update, because it makes $a[0] += 1 behavior the same as
$a[0] = $a[0] + 1.

35d0405c47 Allow random $this on non-internal Closures again 
As it turns out, there is actually no reason to prevent this, it even was a bigger BC break than expected...

Also fixes a memory leak (the Closure leaks) when calling internal functions via Closure by moving it out of leave helper onto caller side for TOP_CODE:

$z = new SplStack; $z->push(20);
$x = (new ReflectionMethod("SplStack", "pop"))->getClosure($z);
var_dump($x());

7e797f1302 Allow an experimental VM with tail call dispatch technique (disabled by default). 
This VM may work only if all tail calls are optimized, otherwaise it will crach because of stack overflow.
Unfortunately, we can't guarantee tail call optimization in C.

b8f56013b5 Force compiler to prefer ZEND_CALL_NESTED_FUNCTION

715d5d2855 Get rid of implicit type casting in GC_*() macros in Zend/zend_types.h. 
This prevented compilation warnings and disclosed few incorrect usages in Zend/zend_vm_def.h and ext/dom/xpath.c.
Now explicit type casting may be required on call site.
This may break some C extension code, but it shoulfn't be a problem to add explicit casting.
