[CodeQuality] Skip mix equal and identical on RepeatedOrEqualToInArrayRector

[samsonasik]

Given the following code:

$a = false;
var_dump($a == 'a' || $a == 'b' || $a === null);

It produce:

-        var_dump($a == 'a' || $a == 'b' || $a === null);
+        var_dump(in_array($a, ['a', 'b', null]));

which invalid on result, see https://3v4l.org/24cFl
