Merge pull request #4459 from ricobbe:build/ricobbe/kill-oacr-warnings-with-a-big-hammer

These warnings typically involve conditional expressions and Boolean operators -- things like  <expr> && 1, <expr> || 1, 'if' condition known to be true, etc.  These can indicate problems, but we do these things intentionally more often than not -- or, at least, sufficiently often that we get a lot of irritating noise from OACR.
