 General: Remove a few `is_object()` checks followed by `instanceof`
 operator.

 This is a minor performance enhancement:

 * If an object is passed, the call to `is_object()` will be redundant.
 * If a non-object is passed, the `instanceof` operator (a variant of
 `is_a()`) will first [https://github.com/php/php-
 src/blob/f42992f/Zend/zend_builtin_functions.c#L630-L631 check if it is an
 object] before doing any further processing.

 Therefore, no additional processing cycles should be wasted in both cases.

 Follow-up to [6779], [48798], [48905], [49194], [55748].

 Props Presskopp, costdev.
 Fixes #58309.
