Bug Type:         Bug
Bug description:RTD collision with opcache

Description:
------------
It is possible to cause RTD key collisions through opcache. Here is a
reproducer using file cache, though the same would also work through
SHM:

file1.php:
<?php
return function() {};

file2.php:
<?php
$file = 'file1.php';
var_dump(include $file);
touch($file);
var_dump(include $file);

Then run file1.php first and file2.php second under -d
opcache.file_cache_only=1.

Actual result:
--------------
Fatal error: Runtime definition key collision for function {closure}.
This is a bug
