Description:
------------
We have a buildtime option HAVE_PCRE_JIT_SUPPORT and a runtime option for pcre2 jit usage PCRE_G(jit)



opcache only honour buildtime option, not the runtime one.


This raise AVC on SElinux enabled system

Test script:
---------------
Start php-fpm service


Expected result:
----------------
No AVC


Actual result:
--------------
type=AVC msg=audit(1611840254.138:10844): avc: denied { execmem } for pid=328163 comm="php-fpm" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:httpd_t:s0 tclass=process permissive=1
