  * Fix issue 19192 - [wrong-code] [crashes] Covariant method interface <-
abstract class <- class hierarchies

  While analyzing covariant methods, dmd semantic analyzer searched for
  immediate interfaces of the class that may have a vtbl entry matching
  the method. This failed for possible scenarios where the covariant
  method may be declared in an interface inheritance of an abstract base
  class.

  The fix adds a for loop that iterates over the base classes to find
  the relevant interface with matching vtbl entry.
