The symbol table is only a tiny part of the information contained in a
.lto file.  Today, liblto would only have the symbol table, and little
by little we would add the rest.

Yes, that's exactly what I was proposing.  And I would not remove the
symbol table, I would simply convert it into something that has the
actual DECLs in it. The symbol table is always useful.
