// A unique identification scheme for Pdb records.
// The scheme is to partition a 64-bit integer into an 8-bit tag field, which
// will contain some value from the PDB_SymType enumeration.  The format of the
// other 48-bits depend on the tag, but must be sufficient to locate the
// corresponding entry in the underlying PDB file quickly.  For example, for
// a compile unit, we use 2 bytes to represent the index, which allows fast
// access to the compile unit's information.
