The buildfarm seems to be happy --- the active members that haven't
reported in should be unaffected by this patch, either because their
compiler versions are too old or because they're not x86 architecture.
So I went ahead and back-patched, and have adjusted longfin to apply
the -fsanitize switch in all branches.
(I've checked that 9.6 passes check-world this way, but not the
intermediate branches, so it's possible something will fail...)
