Greg knows better, but I remember him mentioning that upstream clang
doesn't generate any worse code with -mno-implicit-float, so there should
be no harm in using this workaround with all versions.

This might change in future, of course, so I don't have objections to
adding a check for clang version < 6.0 here.
