  Log Message:
  -----------
  Restore "[LTO/WPD] Enable aggressive WPD under LTO option"

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.
