This restores 59733525d37cf9ad88b5021b33ecdbaf2e18911c (D71913), along with bot fix 19c76989bb505c3117730c47df85fd3800ea2767. The bot failure should be fixed by D73418, committed as af954e441a5170a75687699d91d85e0692929d43. I also added a fix for non-x86 bot failures by requiring x86 in new test lld/test/ELF/lto/devirt_vcall_vis_public.ll.
