Log Message:
README.gcc12: vax boots into multiuser, but c++ things are broken

- vax builds with lots of newly added -O0 workarounds to avoid
  ICE (not committed yet).
- On simh, it successfully boots into multi-user mode.
- C++ exception handling is broken. For GCC 10.5.0 and priors,
  we have local change for libunwind:

  http://www.execsw.org/netbsd/changeset.cgi?id=20140318T234341Z.c59ac4642e7d4b345f6dc5aa9887e9e1f9aa459a#src/gnu/dist/gcc4/gcc/config/vax/vax.c

  But, mechanically applying it (adjusted-for-GCC-10.5.0 version)
  does not help.
- Native gcc cannot compile hello.c due to ICE, even without
  any optimization.
- Sanitizers do not build yet.
