If-Null return/break/... foldable to '?:'

Reports an if expression that checks variable being null or not right after initializing it that can be converted into an elvis operator in the initializer.

Example:

  fun test(foo: Int?, bar: Int): Int {
      var i = foo
      if (i == null) {
          return bar
      }
      return i
  }

The quick-fix converts the if expression with an initializer into an elvis expression:

  fun test(foo: Int?, bar: Int): Int {
      var i = foo ?: return bar
      return i
  }
