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)....

Convenience Instructions</A ></H1 ><P > Similar to the 6800 compatibility instructions (pragma 6800compat) these pragma 6809conv and pragma 6309conv enable convenience extensions to the 6809 and 6309 instruction set. Originally intended for compatibility with the MACRO-80c assembler, these have proven useful in large codebases that target both the 6809 and the 6309.</P ><P > The 6809 extensions are straightforward with the exception of "TSTD" which assembles as "STD -2,S". A benefit of using these is they will "just work" and take on their 6309 equivalent when you enable 6309 assembly mode. Supported instructions: ASRD, CLRD, COMD, LSLD, LSRD, NEGD, TSTD.</P ><P > 6309 extensions are based on common patterns described by Chris Burke and Darren Atkinson in their 6309 documentation and include the following instructions: ASRQ, CLRQ, COMQ, LSLE, LSLF, LSLQ, LSRQ, NEGE, NEGF, NEGW, NEGQ, TSTQ.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x659.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="x805.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Assembler Modes and Pragmas</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="c62.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Cycle Counts</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
