Bug 590486: Remove snarl now that eval is fast again.

In bug 578158, we needed to run entire benchmarks through eval(), but some
benchmark features erroneously prevented the tracer from running. Snarl() was
added to be an eval() without that limitation. Once that limitation was fixed, in
bug 580529, eval() could be used again and so Snarl() wasn't needed.
