Based on our previous discussion
(https://github.com/llvm/llvm-project/pull/90786#issuecomment-2108855275) I
hope we can agree using the attribute this way is problematic. I don't see how
`states` could be have its bounds correctly computed when the compiler doesn't
know how big `struct _ATOM_PPLIB_STATE_V2` actually is.
To unbreak this particular use quickly I'll downgrade the struct with FAM case
to a warning and from there we'll need to decide how to proceed.
