Done (with a couple more patches which are especially floating-point
related).  There were no ICEs.  The additional patches introduce a lot
of churn at -O0; after removing -O0 differences I was able to look at
the changes, and the changes (improvements) are more or less exclusively
what I expected from the additional patches that I included in the test.

Sorry for the informal nature of the description above. :-)
