radv: apply the indexing workaround for atomic buffer operations on GFX9

Because the new raw/struct intrinsics are buggy with LLVM 8
(they weren't marked as source of divergence), we fallback to the
old instrinsics for atomic buffer operations only. This means we need
to apply the indexing workaround for GFX9. The load/store
operations still use the new LLVM 8 intrinsics.

freedreno/ir3: fix lowered ubo region alignment

Since we emit UBO regions INDIRECTly (ie. not copied into cmdstream but
emit by EXT_SRC_ADDR) we need to keep them 4*vec4 aligned.  Which the
code already mostly did, except for aligning the first UBO region itself
(ie. the one after block==0 which is the "real" uniforms).

freedreno/ir3: fix shader variants vs UBO analysis

Otherwise we zero out the state again, but all the UBO loads that we
could lower are already lowered.  End result is that we didn't emit the
uniforms for lowered UBO access in any case where multiple shader
variants are used.
