 `function_exists()` returns false for functions disabled through
 `disable_function` in php.ini.

 Via the discussion on #26772, it seems like it's possible for a false
 positive when using suhosin config to disable. We added an additional
 check for `ini_get( 'disable_functions' )` in [29330], but I'm not sure
 how that works with suhosin anyway, which uses the option
 `suhosin.executor.func.blacklist`.

 It may be that we've done just fine with `function_exists()` on it's own
 beyond that one bug report, but I may also not understand a piece.
