Description:
------------
Having a lot of performance issues on FreeBSD caused an investigation into realpath_cache. It turns out the cache is disabled when safe mode or open basedir are enabled. However, in a client's configuration, with FastCGI and SuExec, realpath_cache poses no security threat. With this cache, performance is greatly improved.

It should be optional to override the decision to disable the cache.

Reproduce code:
---------------
/* Disable realpath cache if safe_mode or open_basedir are set */
if (PG(safe_mode) || (PG(open_basedir) && *PG(open_basedir))) {
        CWDG(realpath_cache_size_limit) = 0;
}


Expected result:
----------------
N/A

Actual result:
--------------
N/A

Real path cache would make some checks unreliable. If you are using 
SuExec or FastCGI you don't need open_basedir, you can use file system 
permissions to implement access limitations much faster & more reliably.
