97857731ce nir: Handle unified atomics in simple cases
Lots of passes can be made unified-atomics-aware simply by adding extra cases in
their switch statements. This commit fixes a bunch of passes.

ffefa386fd nir/lower_task_shader: fix task payload corruption when shared memory workaround is enabled
We were not taking into account that when all invocations within workgroup
are active, we'll copy more data than needed, corrupting task payload
of other workgroups.

f6adfd6278 nir/lower_task_shader: allow offsetting of the start of payload
We need this, because on Intel task payload starts with private header,
followed by user-accessible data.

Fixes: 37e78803d7 ("intel/compiler: use nir_lower_task_shader pass")

8aff8d3dd4 nir: Add common task shader lowering to make the backend's job easier.
1. Lowers NV_mesh_shader TASK_COUNT output to launch_mesh_workgroups.

2. Removes all code after launch_mesh_workgroups, enforcing the
fact that it's a terminating instruction.

3. Ensures that task shaders always have at least one
launch_mesh_workgroups instruction, so the backend doesn't
need to implement a special case when the shader doesn't have it.

4. Optionally, implements task_payload using shared memory when
task_payload atomics are used.
This is useful when the backend is otherwise not capable of
handling the same atomic features as it can for shared memory.
If this is used, the backend only has to implement the basic
load/store operations for task_payload.
