Commit 0719ace6 improves the code
generated for comparisons by avoiding the materalization of the
comparison bit.

Now, this commit aims at doing this same improvement for binary
operations. Since binary operations set the ZF flag, there is no
reason to insert a "== 0" comparison.

Note that this commit might increase register pressure, which might
actually reduce performance. It's hard to anticipate, so we'll land
it, and revert it if it's actually bad for performance.
