All those issues also appear when using -O3, correct? I had a look
and the strlenopt bug should be fixable, but not sure about the
others.

I think omp for simd will set force_vectorize on the loop, we might
want to consider what that should mean for the purpose of selecting
a cost model. There's also the 'vectorize' pragma with a similar
effect. One might argue both cases warrant turning off the cost
model ...?
