I have an ugly script that goes through the dependency files generated by make

There's a clang tool called "include-what-you-use" that does this properly
(http://code.google.com/p/include-what-you-use/).
https://bugzilla.mozilla.org/show_bug.cgi?id=634839 is a bug for using it to
clean up SpiderMonkey's headers, which had progress made but stalled out.
https://bugzilla.mozilla.org/show_bug.cgi?id=772807 was a bug for cleaning up
editor/ which actually completed, thought the build time improvements were
minor.
IME, this is one those things that seems easy and worthwhile but usually ends
up being a real pain, and doesn't seem worth it. Getting it 90% right isn't too
bad but there's often some trouble in the last 10% that torpedoes it.
Someone pointed out a small problem with include-what-you-use: it tries
to include mozilla-config.h although that is of course already
force-included on the command line.
