Replace early_error and sess.err with bug!, in all cases. If the
compiler we're running with, including plugins, is registering something
twice, that's a (compiler/plugin) programmer error -- we should not try
to be nice at the cost of developer ergononomics (hiding the stacktrace
of the second registration is bad).
This also is basically a static bug in ~all cases so it should not be a
detriment to users, including with plugins.
