(after syncing, you will probably want to skip the "download clang binaries"
step if lldb was requested)

Do you want to land this? I'm kinda waiting on the cmdline flag bits for
something else. (If not, I can just copy them into my CL, but I didn't want to
give you merge conflicts)

OK, sure.  I didn't land it because it turns out lldb doesn't build on Linux,
but in principle this is correct and maybe it works on Mac.

Hmyeah, but on mac you need to do weird certificate munging etc. (And
on Lion, lldb is in /Developer/usr/bin anyway.) If it doesn't work on
linux, let's not land it.

Too late!  :P
Since it's off by default, caveat emptor on using the flag...
