An iteration command for traversing advices of a function

[Luis-Henriquez-Perez]

As far as I know, in emacs the way you need to traverse through advices of a function is via advice-mapc. I find it slightly unpleasant to do this. I know loopy as well as cl-loop have iteration commands/clauses for making some iterations convenient (such as numbers). Maybe this is a good candidate for such a command.

(iter (advice-list (advice props) function)
      (when (= advice fn)
	(do-something)))
