FWIW, I also see slowdowns like this on our buildbot:
http://lab.llvm.org:8011/builders/clang-x86-win2008-selfhost/builds/1962
The stage 1 incremental build is 2.5m and the stage 2 build takes 26m. This
is an optimized build with assertions enabled, though, so it's not an
apples-to-apples comparision.
