  We provide fairly detailed decode of ESR for data aborts but do not
currently cover the information reported in ISS2 which has had quite a
bit of additional information added to it by recent architecture
extensions.  Add decode for this information to aid in debugging, for
completeness including features we don't actually use yet.
