That solution is asm-goto. We (linux kernel) are not going to support
something like it. It's going to be asm-goto or bust. The feature is
over 7 years old by now, deal with it.

If you ever get to the point where it makes sense to build a kernel with
LLVM, then you can bike-shed with the GCC team on new features, until
then tough luck.
