Subject: [PATCH] Generic/DeprecatedFunctions: remove redundant
 `method_exists()`

This code snippet was introduced in ec29df437d7ce83bf63f73cdf6c4583b5ea91d8e to allow for running the sniff on HHVM, but HHVM support has been dropped in PHPCS 3.3.1.

In native PHP, the `ReflectionFunctionAbstract::isDeprecated()` method is available since PHP 5.2, so this check is redundant.
