Subject: [PATCH 1/2] AMDGPU: Add test for LDS module lowering removing
amdgpu-no-lds-kernel-id
Prepare to move where AMDGPUAttributor runs. Currently it runs after
LDS lowering, where the lack of kernel ID intrinsics is inferred.

Subject: [PATCH 2/2] AMDGPU: Drop amdgpu-no-lds-kernel-id attribute in LDS
lowering
This is in preparation for moving the run of AMDGPUAttributor earlier.
Currently it infers the lack of the corresponding intrinsic calls,
so if we introduce new ones we need to remove the attribute from any
possible transitive callers. This is more conservative than necessary,
we could try to identify specific subgraphs where LDS globals are not
used.
Other options include teaching the attributor to avoid adding it in cases
where the lowering may choose the table, but this seems more complex.
Alternatively could add a second run which doesn't seem worth it.
