radv: Enable lowering dynamic quad broadcasts.
This will lower dynamic quad broadcasts into something that both LLVM and ACO can understand. On hardware which supports shuffles, they are lowered to shuffle, on older hardware (GFX6-7) they will get lowered to constant quad broadcasts. Fixes dEQP-VK.subgroups.quad.*.subgroupquadbroadcast_nonconst_* Cc: [email protected] Signed-off-by: Timur Kristóf <[email protected]> Reviewed-by: Samuel Pitoiset <[email protected]> Tested-by: Marge Bot <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4147> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4147>
