I think the change makes sense conceptually -- pragma unroll should override pretty much all inlining heuristics, and I don't see a strong reason why it wouldn't override this one as well.

A possible caveat is the interaction with the pre-link pipeline: Are we okay with unrolling the calls there, or would it be better to wait until post-link (in which case the call has likely been inlined)?
