Comments: Use wp_cache_get_multiple in WP_Comment_Query
.
In the `fill_descendants` method in `WP_Comment_Query`, there is a loop the calls `wp_cache_get` to get `child comments. Instead of getting one key at a time, use `wp_cache_get_multiple` and get all keys at once. Props spacedmonkey, tillkruess, mukesh27. Fixes #57803. Built from https://develop.svn.wordpress.org/trunk@55607 git-svn-id: http://core.svn.wordpress.org/trunk@55119 1a063a9b-81f0-0310-95a4-ce76da25c4cd
