Which is exactly what NIR->LLVM was doing but at NIR level. This
pass is already called by ACO.

The number of generated primitives is only counted by the hardware
if GS uses the legacy path. For NGG GS, we need to accumulate that
value in the NGG GS itself. To achieve that, we use a plain GDS
atomic operation.

The former was always true and hence dead code. We will want to
explicitly declare the ring offset register with ACO, but we also want
to declare the scratch offset too, and we can't try to disable it since
ACO also supports spilling and the determination of whether spilling has
to happen occurs well after setting up registers. So replace
supports_spill with something that will actually be used for ACO.

This exposes what's required for DX and this is what we already
configure. The driver flushes denorms for FP32 and preserves them
for FP16/FP64. Note that we can't allow both preserving and
flushing denorms because this won't work for merged shaders. This
will require LLVM to update the float mode register to make it work.
Only enabled on GFX8+ with the LLVM path because it's untested on
previous chips and ACO doesn't support it.

The LDS storage allocated for stream outputs is 4 * N, where N
is the number of outputs. So, we have to store/load with N as index
and not with the output location as index.
This doesn't fix anything known but it should fix out-of-bounds
access and it also reduces the number of outputs written to the
LDS storage.
