removed. This document could still stand for significant improvement:
* Editing the pass descriptions; most were lifted with minimal editing from
comments. Although implementation details were elided, many of the were not
written for the audience that would be interested in this document.
* More "before and after" examples.
* More implicit dependency details. (Perhaps listing transforms in
-std-compile-opts order would help alleviate this.)
* Adding documentation for how to invoke passes programmatically.
* Rearranging the document into a more logical taxonomy. For instance, putting
profiling passes together.
