I don't think this is a planned feature. The C backend does not support all target-specific features, and I
do not believe it is intended to. Maybe a better error message would suffice? Chris?

It would be straight-forward to implement these. The only ones that should be missing are ones we map
in the llvm-gcc front-end. For example, grep for lvx in gcc/config/rs6000/llvm-rs6000.cpp.

More serious is that we don't support vectors in the C backend, so your entire hope is about to be dashed
until we get that. :)
