initialized in this constructor nor in any functions that it calls.

If the workgroup_size variable is lower than the actual workgroup size,
that means it's possible that ACO won't emit some s_barrier instructions
when in fact it should. This can possibly cause a GPU hang.
This is just for the sake of general correctness, currently this
can't cause a real problem because the maximum vertex count is always
greater than (or equal to) the primitive count in GS, and already
takes into account the number of GS invocations.

This is a workaround for a bug in Navi 1x NGG HW.
Very rarely, the Navi 1x PA can hang when an NGG workgroup exports
0 total primitives. According to AMD, we always need this workaround
when it is possible that the number of primitives is 0.

This is to make sure we don't compile a shader which doesn't

The p_reduce instruction only works if this operand is in a VGPR,
and otherwise gets lowered to incorrect code.

Example:
It is possible for some NGG GS waves to have 0 ES and/or GS invocations,
and in that case having an s_barrier inside divergent control flow can
very possibly hang the GPU.

Streams are really stateful and (IMO) difficult to read for non-trivial
usage. This is also more consistent with NIR and the rest of ACO.

The pack_* instructions are now lowered via nir_lower_alu_to_scalar()
and unpack_* are not lowered anymore.
These bitcasts are no-ops, and lowering prevents
some optimizations like vectorization.
Note: There are still some *_split variations remaining
from different other NIR passes.

This is another case of a feature that is implemented in the compiler
and that only required that we set the shader key properly from the
pipeline state, which we were already doing.
I verified we pass the tests in dEQP-VK.pipeline.multisample.alpha_to_one.*
(we only support 4x multisampling, so we can only pass a single test there),
however, the tests seem to have a bug by which they always pass, even if
the driver doesn't actually implement alpha to one correctly. I submitted
a fix to Khronos and verified that we also pass the fixed tests (and that
we failed them if we don't actually set te shader key correctly).

Partial rollback as GFX9 really requires height = 1 to work.
The two substantial parts of the fix remaining:
1) Deal with views with multiple levels.
2) Limit the expansion to the base mip pitch/height. On GFX9 this
is exactly equal to the surf_pitch that was used before. I've
done some investigation to make sure that on GFX10 this always
results in the right physical layout.
Remaining stupid question is how the actual extents for bounds
checking never end up too low when the size gets clamped, but
this change and the previous change don't change that ...
