David, msny thanks for looking at this.

Agreed.  I suppose it's slightly more self-documenting than
NOTE_INSN_DELETED, and it's good to be consistent with other ports.

David, FWIW, a patch to add those two lines is pre-approved.  If you've
already tested the NOTE_INSN_DELETED version, don't feel you need to test
the whole thing again with the other note; as long as cc1 compiles,
that's fine.

Richard
