One way is to use LNT, run the the test-suite twice (w/ and wo your
patch) and use its web interface to check for regressions:
http://llvm.org/docs/lnt/quickstart.html#running-tests

This is a sensitive change, it would be good to see where the
heuristic win/lose so we can be sure it's worth it. I'm gonna give it
a run here too and let you know what I find.
