Changeset 51018 for trunk/src/wp-includes/post.php

Message:

Posts, Post Types: Speed cached get_pages() calls.

This improves performance for sites with persistent cache backend having a lot of pages requested via the get_pages() function, by taking advantage of wp_cache_get_multiple()` instead of fetching each individual page from the backend cache server one by one.

It also matches the behaviour of get_pages() when the pages are retrieved from the database.

Props david.binda, hellofromTonya.
Fixes #51469.
