Using av_assert1() or av_assert2() will yield a performance hit, but only
when enabled in development builds.

But I agree with Hendrik, it should only be done when the correctness of the
code is not obvious for a reasonably smart human reader. If the compiler is
not smart enough to see it, then it only means it is too early to enable
that warning.
