DEFAULT_VERSIONS+=llvm=70 (already default) syntax would apply to mesa-dri
after v2 in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230789 lands.

Once devel/llvm80 appears it'd be time to prepare for LLVM_DEFAULT bump,
patching consumers and asking port maintainers for feedback until actual
release happens. Based on results consumers not ready would be temporarily
kicked out from LLVM_DEFAULT train, or maybe someone provides a better idea.
llvm80 stabilization is partially dependent on how much help clang800-import
effort receives.

Note, LLVM_DEFAULT is defined in Mk/bsd.default-versions.mk
