-----------
New exception handler adoption with fallback
https://bugs.webkit.org/show_bug.cgi?id=271489
rdar://119256062
Reviewed by Per Arne Vollan.
Patch by Brandon Kayes and Keith Miller.
This adopts the new hardened mach exception mechanism which was
introduced in darwin recently. See the radar for more details.
This attempt to land this patch should work with stale sandbox
profiles, which was causing problems with the previous iteration.
