Investigate MSVC's Return Flow Guard
/guard:rf Literally brand new in 15.5.3 so no one knows what it does or how it works. MSFT will release more information eventually, I just don't want to forget about it.
Perf results are in: https://treeherder.mozilla.org/perf.html#/compare?originalProject=mozilla-central&newProject=try&newRevision=cd0d24d4447b42c9bf013d3b65940dfad746246f&framework=1&selectedTimeRange=172800 It's pretty sizable regressions all across the board. Except for stylebench for some weird reason.
