LGTM, thanks MaskRay, I was just trying to using same approach as I fixing at binutils side to fix LLVM, but I apparently lack of global view on the MC layer, so I didn't aware there is more place need to adjust.

And I have to say those relaxation corner case is really terrible even I am a RISC-V guy...
