Description:
------------
For PHP-FPM settings with large memory size configurations, a large portion (70%-90%) of the opcache
memory is reported as "used" even directly after restarting PHP-FPM without any php
scripts cached.






Test script:
---------------
To reproduce: 

* configure your php.ini:

php_admin_value[memory_limit] = 1G
php_admin_value[upload_max_filesize] = 1G
php_admin_value[post_max_size] = 1G

; OpCache Bytecode caching
php_flag[opcache.enable] = on
php_flag[opcache.enable_cli] = on
php_admin_value[opcache.memory_consumption] = 512M
php_admin_value[opcache.max_accelerated_files] = 50000


* restart PHP-FPM
* look at opcache memrory used value.

Expected result:
----------------
At least directly after PHP restart, it should not be dependent on memory size configurations

Actual result:
--------------
phpinfo() : 

Used memory 	206827696
Free memory 	61607760
