This revision now requires changes to proceed.

Sadly I missed your last comment and this has languished :/.

If you are still interested in pursuing this, I suggest adding setvector semantics to NamedMetadata as an option, and then this patch is just migrating llvm.ident to it. A couple of comptions for syntax include:

  !name{} = !{!0}
  
  !name{uniqued} = !{!0}
  
  !name! = !{!0}
  
  !name& = !{!0}
  
  !name &= !{!0}
  
  !name |= !{!0}

Please CC me on the RFC to llvm-dev.
