This optimization has been done with dyngen in mind, we surely don't
want to keep it with TCG.

I currently have plenty of time, but almost no network (travelling), so I'll work on implementing a solution, and commit the result most probably
tomorrow morning.

I already have a solution cooking for cpu_T64 and SPE, including improved TCGv setup. It'll be no problem for me to incorporate your and Thiemo's comments in my revised patch.

SPE will be rarely used anyway I guess, so I think it's relatively "safe" for me to remove the dyngen optimization and simplify ppc_gpr_t during this transition. Since you requested larger patches, I started to merge gpr64 into it and was planning to convert the stores as well in one go. It doesn't sound too promising if we both make changes at the same places now...
