The initial version of this commit used `not`: https://github.com/llvm/llvm-project/commit/cbd28cd05bb11e9d76d71c6cc2d38d89dbb1fe1a but for some reason that was changed in https://github.com/llvm/llvm-project/commit/a30a4a35ecbd2ebff79de8a193e7045b17da3ff5 

Maybe removing `not` was used to work around the missing `UNSUPPORTED:` that was only added in https://github.com/llvm/llvm-project/commit/307daa71a8f0bb258d4c89d5bad2579f468162ca CC: @serge-sans-paille @hahnjo 

I'd be tempted to restore this to using `not` instead of `|| :` and see if the builders are happy.
