This is actually fixed now.
This change requires LLVM r358579. Make sure to have it in
your tree, otherwise the following piglit will hang:

Use the raw version (ie. IDXEN=0) because vindex is unused.
Use the old intrinsic for compare&swap because the new one
hangs the GPU for some reasons.

In radv we had a separate flag to actually use it + an env option
to experimentally use it.
The common code setting has_local_buffers to false of course broke
that experimental option.
Also the "enable on APU" did not make sense for RADV as it is still
disabled by default.

currently seems to be no issue with skipping it, we will have to
