If those were "Compile-time arithmetic does not support these semantics"
assertion failures, then my long double patches would indeed have been
the fix ...

However, I actually don't quite understand how this could have affected
LLVM tests; on Linux, only Clang tests were affected (those where the
source code used long double constants).
