ReflectionMethod::__construct() overwrote intern->ptr without releasing the previous Closure::__invoke() trampoline, and ReflectionClassConstant::__construct() overwrote the $name and $class slots without dropping their previous references. ReflectionFunction, ReflectionParameter and ReflectionProperty already release prior state on re-entry. Closes phpGH-22968

The result was ignored, so calling the factory on an uninstantiable subclass ran on a NULL zend_object: object_init_ex() throws, sets the return value to NULL and reports FAILURE, and Z_REFLECTION_P() then offsets backwards from that NULL. Three other object_init_ex() calls in this file already test the result. Closes phpGH-22978

instantiate_reflection_method()ignores the result ofobject_init_ex(). On an uninstantiable subclass that call throws, sets the return value to NULL and reports FAILURE, and the helper then runsZ_REFLECTION_P()over the NULLzend_object, offsetting backwards out of the allocation.Segfaults on 8.4, 8.5 and master; 8.3 carries the same code.
ReflectionClass::newInstance(),newInstanceArgs()andnewInstanceWithoutConstructor()already test the result the same way. Found while reviewing php#22968, which touches the same helper but does not cause this.
