xhprof does not support PHP7, and it doesn't seem like upstream will be working on that any time soon. Tideways is a profiler that is basically a drop-in replacement for xhprof with functions renamed. So Xhprof::enable() and Xhprof::disable() will now try to use tideways if that is installed and xhprof is not. Bug: T152186 Change-Id: I0d7d2de56ac638ca2851c662f527049bd620c0e9
