With this patch, if there is a function which is only inlined (there is
no "out-line" copy), will "break function" still work?

It seems to me that it wouldn't always, because there wouldn't be a
partial symbol to match.  Maybe it might work accidentally if the inline
function appears in a CU that is already expanded, like main's.  So the
test would have to be an always-inline function that isn't used in
main's CU.

If it does work, then I wonder how, since my mental model is that all
the paths to expansion require a matching partial symbol.

If it doesn't work, then I think a different fix is needed.

thanks,
Tom
