remove unused symbol Ident{Start,End} fields. The ident start/end is now stored as a ref with def=true. Previously, graphers had differing behavior; some stored def refs, some did not, and some set identstart/end, and some did not. By removing them from Symbol, where they are not needed, we eliminate the confusion.
