I've realized I have a concern.  Grepping (or searching in an editor 
buffer) the log file for 'internal compiler error' to find actual 
regressions is a thing I want to still be able to do (perhaps with 
alternative spelling, I don't care).  I don't want to see the ICEs of 
tests that are expected to ICE.

I think that means there has to be a positive marker on the unexpected 
ICEs, rather than lack of an expected marker on them.
