Doing a search at LXR, I've found this
http://lxr.php.net/source/php-src/main/php_variables.c#579
JIT is controled by this:
zend_bool jit_initialization = (PG(auto_globals_jit) &&
!PG(register_globals) && !PG(register_long_arrays) &&
!PG(register_argc_argv));
So, you need auto_globals_jit enabled, as well register_globals,
register_long_arrays and register_argc_argv disabled.
Looking below, we can check that it is only applied to $_ENV and to
$_SERVER. $_POST, $_GET and $_COOKIE seems not to implement this JIT
initalization.
$_REQUEST seems also not to be initialized when 'jit_initialization' is
true.
But to be sure, just make a bit of testing :)
