icc's good performance on Kahan's Paranoia benchmark is surprising given
that it makes obviously unsafe floating point transformations; a
reasonable conclusion is that its developers were asked for both a good
Paranoia score and good floating point performance, and they cut corners,
but took care not to break Paranoia.
