From 24128dfc902f6036d664015cd10943eba8fa9436 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Posts: Add the `pre_get_lastpostmodified` filter to
 `get_lastpostmodified()`.

This allows `get_lastpostmodified()` to be short circuited when the site wants to avoid running the occasionally slow queries in `_get_last_post_time()`.

Fixes #34205.
