dlang/dmd pull request #13267 "Fix 21538,20904: Correct implicitConvTo order
for delegate parameters in `Type.covariant`" was merged into master:

  Fix 21538,20904: Correct implicitConvTo order for delegate parameters...

  ... in `Type.covariant`

  The ordering was inversed when compared to function pointers. That caused
  the check to accept e.g. less restrictive attributes for callbacks.

  Also changed the equality checks for `TypeFuntion` and `TypeDelegate`
  to `equals` because `==` didn't call the former and hence caused problems
  for duplicate instances.
