Support failed JIT test case: fetch_obj_004.phpt

Opcode ASSIGN_OBJ is generated for statement "$x->a = 1;" and one new
path in function zend_jit_assign_obj() is covered. Note that function
zend_jit_assign_to_variable_call() is invoked along this new path.

Besides, helper function zend_objects_store_del() is used as the dtor
for objects.
