The perf difference is very small: 0.99% -> 0.40% for the time spent
in si_get_ia_multi_vgt_param when si_draw_vbo is 20%. Pretty much nothing.

We can hardcode all of the fields for swizzling in the geometry shader.
The advantage is that we use fewer descriptor slots and we no longer have to
update any of the (ring) descriptors when the geometry shader changes.

Fixes GL45-CTS.geometry_shader.adjacency.adjacency_indiced_triangle_strip and
others.
This leaves the case of triangle strips with adjacency and primitive restarts
open. It seems that the only thing that cares about that is a piglit test.
Fixing this efficiently would be really involved, and I don't want to use the
hammer of degrading to software handling of indices because there may well
be software that uses this draw mode (without caring about the precise
rotation of triangles).
v2:
- skip the GS prolog entirely if workaround is not needed
- only check for TES (TES is always non-null when tessellation is used)

The copy shader only depends on the selector. This change avoids creating
separate code paths for monolithic vs. non-monolithic geometry shaders.

I guess this is not needed because dead code elimination removes

Note that for indirect draws, the new MULTI firmware packets are required.
There's also no need to reset last_{start_instance,sh_base_reg}, since
resetting last_base_vertex is sufficient.

Prefer to use DRAW_(INDEX)_INDIRECT_MULTI when available in the firmware.
Versions for SI and CI already added as provided by the firmware team, but
keep in mind that they won't currently be used since the radeon kernel module
has no interface to query the firmware version.

Unlike SC, the small primitive filter does not automatically use center
locations in 1xAA mode, so this is needed to avoid artifacts caused by
the small primitive filter discarding triangles that it shouldn't.
As a side effect of how the effective number of samples is now calculated,
this patch also avoids submitting the sample locations for line/poly smoothing
when they're not really needed.

Main shader parts and geometry shaders are compiled asynchronously
by util_queue. si_create_shader_selector doesn't wait and returns.
si_draw_vbo(si_shader_select) waits for completion.
This has the best effect when shaders are compiled at app-loading time.
It doesn't help much for shaders compiled on demand, even though
VS+PS compilation should take as much as time as the bigger one of the two.
If an app creates more shaders, at most 4 threads will be used to compile
them.
Debug output disables this for shader stats to be printed in the correct
order.
(We could go even further and build variants asynchronously too, then emit
draw calls without waiting and emit incomplete shader states, then force IB
chaining to give the compiler more time, then sync the compilation at the IB
flush and patch the IB with correct shader states. This is great for
compilation before draw calls, but there are some difficulties such as
scratch and tess states requiring the compiler output, and an on-disk shader
cache will likely be a much better and simpler solution.)
