[CGEN PATCH] Rename TRACE_{EXTRACT,RESULT} to CGEN_TRACE_{EXTRACT,RESULT}

[Doug Evans <dje@google.com>]

Hi.

This patch updates the generator so that the next time
the files are generated we don't lose the TRACE_{EXTRACT,RESULT}
renaming change.

ref:
https://sourceware.org/ml/gdb-patches/2015-06/msg00280.html

Tested with:

1) put guile 1.8.8 in $PATH

2) apply this patch:

https://sourceware.org/ml/gdb-patches/2015-06/msg00395.html

3)

bash$ $src/configure --prefix=$(pwd)/rel \
     --enable-cgen-maint \
     --enable-targets=all \
     --enable-sim
bash$ make all-sim

I had to disable building of sim/m68hc11, and make a minor tweak to  
sim/moxie,
so that their builds would complete.
