Subject: Fix unused variable warnings from clang.

If you enable -DSTRICT=ON in cmake and also build with clang, it
reports a couple of variables set but not otherwise used. One was
genuinely unused ('loop_found' in loop_deductions in Loopy); the other
is used by debug statements that are usually but not always compiled
out.
