Add emuext pragma and associated instructions. This provides two emulator specific instructions ("log" and "debug") enabled by the "emuext" pragma. This is from a patch provided by tim Lindner <tlindner@macmess.org>. From Tim's submission: ---- I stole the whole patch from Erik Gavriluk. I hope he doesn't mind. :) The two instructions are "debug" and "log". They are enabled with pragmas. I also added them to the manual. Hopefully all is well. ---- Said Erik Gavriluk <erik@bombfactory.com> in response: ...happy to see them picked up in mainline (if you choose to do so)....
