Role of DejaGNU?

I see mentions of DejaGNU sprinkled around the tree. Do we still need
it? If so, what role does it play? If not I'll sanitize docs and code
that reference it.

You need it to run the tests in
http://llvm.org/viewvc/llvm-project/clang-tests/trunk/ (the gcc and
gdb testsuites). We don't use it for anything else.
