Description:
------------
I bumped into the issue that with php5.4, apc enabled and having 
auto_globals_jit=Off the second request (after it is cached by apc) can be missing 
variables from the $GLOBALS superglobal. 

See the attached file for a reproducible testcase(it is weird, but without that 
sleep call the test sporadically passes), and I also managed to eliminate the bug 
via removing the two PG(auto_globals_jit) checks from apc_compile.c, but I'm not 
sure that it is the best solution(altough it didn't break any tests).
Another thing worth nothing that it seems that the same thing was changed/fixed in  
opcache/ZendOptimizer+:

Test script:
---------------

    if (PHP_MAJOR_VERSION < 5 || (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION < 4)) {
		die('skip PHP 5.4+ only');
	}

$tmp = 'bug_auto_globals_jit_off.tmp.php';
$tmp_file = dirname(__FILE__) . DIRECTORY_SEPARATOR . $tmp;

$file =
