radv testing patch

Hey Samuel,

I re-tested this (on Tonga) with the latest LLVM trunk and the attached patch.
Using RADV_DEBUG=nocache,shaders,ds128 shows assembly that uses the 128-bit
instructions without rendering artifacts.

Looks like we could try enabling this in LLVM by default again, any objections?
