Type visitor code had already been refactored previously to decouple the visitor and the visitor callback interface. This was necessary for having the flexibility to visit in different ways (for example, dumping to yaml, reading from yaml, dumping to ScopedPrinter, etc). This patch merely implements the same visitation pattern for symbol records that has already been implemented for type records. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@283609 91177308-0d34-0410-b5e6-96231b3b80d8
