Please consider taking out some of the unrolling; I suspect it'd not increase time by very much but would greatly reduce the code cache pollution. It's very tempting to unroll everything to make a benchmark run quickly, but we have to take a balanced approach.

But there's only ever one of these generated at startup, right? It's not like the string intrinsics that are expanded at every call site.
