ac_shader_args will be similar to ac_shader_abi, except for being free
from LLVM-specific concepts and therefore capable of being shared
between LLVM and ACO. This will help us accomplish a few different
things:
- Decouple setting up SGPR and VGPR arguments from translating to LLVM,
so that we can reference these arguments in NIR lowering passes, which
will let us lower e.g. descriptor sets in NIR.
- Stop using radv-specific structures for things like determining the
chip generation in ACO.
In the end, we should replace ac_shader_abi with this structure +
driver-specific lowering passes.

Fixes dEQP-VK.compute.builtin_var.local_invocation_index with
RADV_PERFTEST=cswave32.
My initial fix was to lower it but Rhys suggested the shift-right
and it's much better like this.

This fixes some crashes with dEQP-VK.descriptor_indexing.* when
read_first_invocation has its source from a descriptor.
Most of these tests still fail because of an LLVM bug (they work
with ACO).

Because some instructions will be optimized by the backend compiler,
the driver has to manually flush to zero to keep the result exact.

This commit is a step towards the goal of being able to build RADV
without LLVM. In the future we would like to offer the option to
use RADV solely with ACO. There is still a need for the common AMD
code located in amd/common but the LLVM specific parts need to be
separated.
