  • Build a static table of octal strings and use it instead of building octal strings repeatedly during printing.
  • Print a newline and an offset for every 64 bytes in the case of printing array literals so it's easier to locate variation in snapshot blobs.
  • Rework the printing routines so that the differences are only made in a WriteByteVectorLiteral routine. We can update this for compression support in the future.
  • Rename Snapshot::Generate() that write the data as C++ source instead of a blob as Snaphost::GenerateAsSource() for clarity, and move the file stream operations into it to streamline error handling.
