+1 for cherry-picking. Not all tests make sense to run in all
standards (C11 ones, for instance), but some would certainly benefit.
Maybe the ones that don't specify an -std flag would be good to run on
all standards? How would we do that? By changing the semantics of
%clang? Or by enforcing people to duplicate all RUN lines with all
standards?

It seems non-trivial to enforce this...
