Summary

This was only used for checking if is_shared/is_private were legal,
which we're not bothering to do anymore.

This is apparently visible to more than the target attribute (which
seems to silently ignore unrecognized features), so this has the
potential to break something (i.e. see the OpenMP test change)

The OpenMP part is fine.

The code looks fine, but as you say, the change visible in user code and could break something. Do you want to handle that somehow? Maybe wait for @b-sumner

clang/test/OpenMP/metadirective_device_isa_codegen_amdgcn.cpp
17	Was the "dpp" attribute chosen arbitrarily?

OpenMP assumes flat pointers all over, so if someone was relying on this behavior it wasn't doing anything useful. They had dead code

clang/test/OpenMP/metadirective_device_isa_codegen_amdgcn.cpp
17	Yes, also meaningfully varies

I can't verify the idea that users of the behavior had dead code, but assuming that's right LGTM.
