Added an experemental ability to move PHP code pages (PHP TEXT segment) into HUGE pages.
PHP should be configured and built with --enable-huge-code-pages, OS should be configured to provide huge pages.
It's possible to enable/disable this future in php.ini through opcache.enable_huge_code_pages=0/1.
The feature was tested on Linux and provided 2% improvement on real-life apps, because of 2-3 times reduction in number of iTLB misses.
