This is a very, very large commit.  It should have been split into
multiple commits addressing separate issues.  However, in the
description one thing stands out:

> * lisp/files.el (dir-locals-file): Allow wildcards

Depending on how the wildcard search is organized, this may make the
decisive difference.

Can people split the timing tests into user and system time?  Because if
the directory search is at fault, it may be the system time that hits
