Subject: [PATCH] Add a helper function for incrementing the `count` of cached
 ImageMasks

While working on PR 14825, I couldn't help noticing that the code to increment the `count` for cached ImageMasks was repeated multiple times. Hence it makes sense, as far as I'm concerned, to move this into a helper function instead.
