[HEADS UP] Clang 8.0.0 upgrade on 13.0-CURRENT

Mon Mar 4 23:21:32 UTC 2019

Recently /projects/clang800-import branch was merged[1] into /head.
13.0-CURRENT now comes with Clang/libc++/LLD 8.0.0 (RC3 atm) in base.
Many ports have been fixed in advance but many also remain[2] broken.
If you receive mail from pkg-fallout@ one of your port no longer builds
on head-*-default jails or the package you're using is no longer
available this maybe the cause.
