Yes, sorry I should have included more context. It was actually the
Clang Linux folks who noticed it and reported it to us:

There's an LLVM bug filed:

And I think there's now agreement that the Clang behaviour is not
correct, Nick actually sent a revert as well but I already had one

Arnd identified some work arounds, which we may end up using, but for
this cycle we thought it was preferable to just revert this change as it
didn't actually change code generation with GCC anyway.
