[PR middle-end/117263] Avoid unused-but-set warning in genautomata
This is a trivial bug where a user wanted to define NDEBUG when building
genautomata, presumably trying to debug its behavior. This resulted in a
unused-but-set warning which caused the build to fail.
Dario included the trivial fixes in the PR which I put through the usual
bootstrap & regression test as well as compiling genautomata with NDEBUG.
Pushing to the trunk.

* genautomata.cc (output_statistics): Avoid set but unnused warnings
when compiling with NDEBUG.
