[patch] New opcode support for tic4x - part I

[Svein E. Seldal]

Hello,

New opcodes are committed into the CVS. Testsuites are updated 
accordingly. Except from documentation, the tic4x is now considered 
complete. Please do test this target.

Are there special requirements to the gas documentation? That is, do the 
documentation (in the upcoming gas/doc/c-tic4x.texi) need to be at a 
special quality-level before it can be hooked into the global files 
(gas/doc/all.texi and gas/doc/as.texinfo)? I see that there exists 
documentation for a lot more targets than what is included into the as 
manual per. default. What is the ordinary pratice for this?
