We already use GFX9 and I don't want us to have confusing naming
in the driver. GFXn naming is better from the driver perspective,
because it's the real version of the gfx portion of the hw. Also,
CIK means Bonaire-Kaveri-Kabini, it doesn't mean CI.
It shouldn't confuse our SDMA, UVD, VCE etc. code much. Those have
nothing to do with GFXn and they have their own version numbers.
While ImageFormatProperties returns the number of internal descriptors,
it turns out that applications do not need to actually allocate more
descriptors in the descriptor pool.
So if we make descriptors with more planes larger we have to be
convervative and always allocate space for the larger descriptors
which is a waste given the low usage of this ext.
So let us make use of the fact that 3plane formats all have the
same formats & dimensions for the last two planes. This way we
only need the first half of the descriptor of the 3rd plane and
can share the second half of the second plane.
This allows us to use 16 bytes for the descriptor which nicely
fits into the 16 bytes that are unused right next to the sampler.

Because the new raw/struct intrinsics are buggy with LLVM 8
(they weren't marked as source of divergence), we fallback to the
old instrinsics for atomic buffer operations only. This means we need
to apply the indexing workaround for GFX9. The load/store
operations still use the new LLVM 8 intrinsics.
The fact that we need another workaround is painful but we should
be able to clean up that a bit once LLVM 7 support will be dropped.
This fixes a GPU hang with AC Odyssey and some rendering problems
with Nioh.

Basically just reserve the memory in the descriptor sets.
On the shader side we construct a buffer descriptor, since
AFAIU VGPR indexing on 32-bit pointers in LLVM is still broken.
This fully supports update after bind and variable descriptor set
sizes. However, the limits are somewhat arbitrary and are mostly
about finding a reasonable division of a 2 GiB max memory size over
the set.

Seems like dxvk used integer builtins without setting the flat
interpolation decoration.
I believe in the current spec the app is required to set these,
but in the meantime to avoid breaking things in stable releases
(and so close to release for 19.0), only expand the interpolation
to float16 and struct (which cannot be builtins as our spirv parser
lowers the builtin block).

This removes some scalar loads from shaders, but it increases
the number of SET_SH_REG packets. This is currently basic but
it could be improved if needed. Inlining dynamic offsets might
also help.
