OK, I've gone through the source tree and removed all the dead files and reversed all whitespace changes to reduce the number of files which appear in the GCC patch.

I've also found a use for that SB instruction I've mentioned a few times. That will be used to replace an "ANDI Rn, >00FF" instruction. I don't think that constant will be used very often, but this was mostly done to make me feel better.

All ready for release!
