DSP-LLE: calculate code CRC _before_ swapping endianness

- Makes DSP-LLE code checksums the same as those from DSP-HLE. I'm
  assuming DSP-HLE was doing it correctly, since there are numerous
  references to these pre-endian-swapped checksums (including in
  DSPHost.cpp itself).
- Fixes disassembly when dumping code from DSP-LLE, which was using the
  wrong endianness and giving totally bogus output.
- Reveals error messages of the format, "Bah! ReadAnnotatedAssembly
  couldn't find the file ../../docs/DSP/DSP_UC_AX_07F88145.txt," which
  seems to be intended behavior that was previously hidden.
