This is a bunch of instruction and register additions, improved SMT
support, etc. for TCG.

Since v1:
- Not reposting the trivial memop patches that got reviews.
- Fix checkstop reason printing (Richard)
- Fix the attn instruction checks (Richard)
- Don't allocate tcg temp before SMT and serialization checks
  in spr_core_write_generic32() (Richard)
- Move attn to decodetree.

Thanks
Nick
