Description:
------------
I use uopz_redefine to redefine class constants
(uopz called zend_declare_class_constant)

when opcache is enabled, I cannot get the new class constant through Foo::BAR.

Test script:
---------------
<?php

class Foo
{
	const BAR = '123';
}

var_dump(Foo::BAR);// A1: try to comment this

(function () {
	var_dump(Foo::BAR);	// B1: try to comment this
	uopz_redefine('Foo', 'BAR', '456');
	var_dump(Foo::BAR);	// B2: compare
})();

(function () {
	var_dump(Foo::BAR);	// new scope
})();

var_dump((new ReflectionClass('Foo'))->getConstant('BAR'));	// also OK

var_dump(Foo::BAR);	// A2: compare


Expected result:
----------------
'123'
'123'
'456'
'456'
'456'
'456'

Actual result:
--------------
'123'
'123'
'123' (it is '456' if line B1 is commented)
'456'
'456'
'123' (it is '456' if line A1 is commented)

Yes, I'm sure I load uopz before OPcache.

I'm reclassifying this as uopz issue.  If this still happens with
latest uopz (6.1.2) and any of the actively supported PHP
versions[1], please file a bug report at
<https://github.com/krakjoe/uopz/issues>.
