Message:

Comments: Ignore hierarchy in pagination calculation when comment threading is disabled.

In order to calculate comment pagination when newest comments are displayed
first, comments_template() must perform a separate query to determine the
total number of paginating comments available on a post. See [34729], #8071,
pagination calculation - can be defined as a top-level comment, or a comment
with parent=0. However, when comment threading is disabled, yet comments
exist in the database that have parents, all comments - even those with a
parent - are "paginating". (This typically happens when comments threading was
once enabled, but has since been turned off.) As such, the total-paginating-
comments query should only be limited to top-level comments when
'thread_comments' is disabled.

Merges [36275] to the 4.4 branch.
Props jmdodd.
Fixes #35419.
