PresShell::DecVisibleCount() just iterates over all the frames in a visible frames set and decrements a counter for each one for which visibility tracking is still enabled. We'll soon need to add more code that does this kind of iteration, so it makes sense to replace DecVisibleCount() with a general iterator function that takes a lambda as an argument.
Created attachment 8748433 [details] [diff] [review] Replace PresShell::DecVisibleCount() with a general map function. Here's the patch. We'll be making use of this map function a good deal in upcoming patches.

I backed this bug out on inbound, I expect the backout to get merged to mozilla-central. I plan to also request uplift to backout on aurora (so this bug would not be landed in any version of Firefox). Bug 1284350 tracks the back out.
