filter_input and auto_globals_jit

Here is an oddity which I'm not sure how this is supposed to work.

If you have auto_globals_jit enables then not only are super global
variables not initialized unless they are called, the underlying data
storage for the original data[used by filter_input] will not be
populated.

So the question is, is this by design? In which case I'll update the
docs. Or is this an oversight? In which case I'll open a bug and
submit a patch.
Looks like a bug. After all, filter_input is using the variables.

As I read filter.c, there seems to be a weird schism on how it deals with
this.
https://github.com/php/php-src/blob/master/ext/filter/filter.c#L526

For INPUT_SERVER and INPUT_ENV it seems as if filter will make sure to
initialize the data, example:
if (PG(auto_globals_jit)) {
zend_is_auto_global("_SERVER",
sizeof("_SERVER")-1 TSRMLS_CC);
}

For INPUT_POST, INPUT_GET, and INPUT_COOKIE however there is no safety net.

For example, with Just in Time:
test.php?var=test

$before = filter_input(INPUT_GET); // $before = null
$var = $_GET('test'); // $var = 'test'
$after = filter_input(INPUT_GET); // $after = 'test'

So the question is, is this by design? In which case I'll update the
docs. Or is this an oversight? In which case I'll open a bug and submit a
patch.
