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.

...happy to see them picked up in mainline (if you choose to do so)....
