Instrs: 62773 -> 62664 (-0.17%); split: -0.18%, +0.00%

PreSGPRs: 3554 -> 3520 (-0.96%)
Fossil-db changes are probably because v_sub_f32_dpp(v_mul_f32) is no
longer being combined into MAD and then split back into separate
instructions.

It doesn't make sense to ask for the depth-only or stencil-only format
if there is no depth or stencil. One bit of radv_image.c did seem to
take advantage of the default case in vk_format_depth_only so throw an
`if (vk_format_has_depth(format))` around it.

Navi 10 can hang when an NGG workgroup has no output,
so we work around that by always exporting a single zero-area
triangle with a single vertex that has all-NaN coordinates.
Thus far, we only employed this for NGG GS, because on all
other stages, the output can't be empty.
However, with NGG culling, the output can be empty, so let's
apply the same workaround there too.
