compiler: avoid wasteful substitution via %bin-op%.
* share/txr/stdlib/compiler.tl (%bin-op%): Specify default
value argument to relate so that arguments not found in
%nary-ops% will match to nil. Otherwise the code in
comp-fun-form rewrites all two-argument function calls through
this relation, resulting in a bit of wasted consing.
