This only adds support for writing hash values of the record types we currently understand.  For all other record types, we write a hash value of 0.  A quick look at a PDB generated by Microsoft confirms that they have actual values for every single recofd type, so we will likely need to do some more work to figure out how to hash these other record types.  It's probably as trivial as just applying one of these hashing functions to the entire record contents, mostly just need to try it and see.
