When `-Werror` is on, we'd like to see all the warnings before the
 compilation aborts.  At the moment, if a given stage of the compiler
 generates warnings (e.g. the renamer), we stop right there and don't go on
 to do further stages, even though we could.  This isn't completely trivial
 to fix, we need to remember somewhere that warnings were generated
 earlier, or remember the warnings themselves.
