Respin of old series...

Since v1 [*]:
- Fixed '!is_double' check (rth)
- Rebased (removing tcg_temp_free calls)
- Simplified MULT[U].G (rth)
- Added R-b

Cover from v1:

  Loongson is next step in the "MIPS decodetree conversion" epic.
  Start with the simplest extension.

  The diffstat addition comes from the TCG functions expanded.
  The code is easier to review now.
  IMO this is also a good template to show how easy a decodetree
  conversion can be (and how nice the .decode file is to review) :P

Please review,

Phil.
