LGTM.



================
Comment at: llvm/docs/ReleaseNotes.rst:158-159
 * Support ``half`` type on SSE2 and above targets.
+* Support ``rdpru`` instruction on Zen2 and above targets. The ``-m[no-]rdpru``
+  option to Clang controls this independently of the target processor type.
 
----------------
Nit: It's no ideal to put Clang info here. Maybe move it to Clang's Release Notes?
