Obsolete debug symbol file creation using Mono.CompilerServices and AssemblyBuilder.Save

[johnwaynecornell]

Since the advent of portable pdb's and Microsoft's involvement. Mdb's are essentially obsolete and are quite useless to me. I can't find dev tools they will work with. If you want to retain all the glory of the .net framework, please write a Mono.CompilerServices2 that can be referenced so AssemblyBuilder.Save leads to the production of a useful pdb.
