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.
