Bug description:getenv affected by auto_globals_jit in fpm-fcgi SAPI

Description:
------------
If the auto_globals_jit directive is enabled the getenv function does
not return all of the environment variables.

The test script below must be executed with the fpm sapi.  I personally
tested this with both Nginx and Caddy + php-fpm.  It doesn't seem

If you access a superglobal anywhere in the script (even after the
getenv call), the environment variables are loaded as expected.

The value of the fpm directive clear_env does not seem to matter.

PHP version:

PHP 7.3.3 (cli) (built: Mar  8 2019 16:40:07) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.3, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.3.3, Copyright (c) 1999-2018, by Zend
Technologies

(installed with Homebrew)

Relevant ini params:

variables_order = "EGPCS"
auto_globals_jit = On

Test script:
---------------
<?php

var_dump(getenv());

// Uncomment this and the environment variables are returned above
// $whatever = $_ENV['SOMETHING'] ?? false;

Expected result:
----------------
When I execute curl localhost I see the output:

array(28) {
  ["USER"]=>
  string(4) "matt"
  ["HOME"]=>
  string(11) "/Users/matt"
  ["HTTP_CONNECTION"]=>
  string(10) "keep-alive"
  ["HTTP_ACCEPT"]=>
  string(3) "*/*"
  ["HTTP_ACCEPT_ENCODING"]=>
  string(13) "gzip, deflate"
  ["HTTP_USER_AGENT"]=>
  string(12) "HTTPie/0.9.9"
  // lots more keys ....
}

Actual result:
--------------
When I execute curl localhost I see the output:

array(2) {
  ["USER"]=>
  string(4) "matt"
  ["HOME"]=>
  string(11) "/Users/matt"
}
