title: Is there a way to find all overrides of a PsiMethod?
body: <p>I am developing a plugin for Intellij IDEA 2018.2+.</p>
  
  <p>I need to find all overrides for a given method.
  I tried searching among various <code>PsiUtil</code>classes to find overrides of:</p>
  
  <ul>
  <li><code>PsiMethod</code></li>
  <li><code>PsiClass</code>- to later manually scan methods of overriding class to find whether there are some overriding methods</li>
  </ul>
  
  <p>and yet no luck.</p>
  
  <p>So overall - what is the simpliest way to find all overrides of a given <code>PsiMethod</code>?</p>
