function-static <https://pastebin.com/zJNEtQyL> vs global-static <https://pastebin.com/CADwLPAH> TLS variables: http://quick-bench.com/te2xYFbzDW0dqt-ql0fOQMieFEM

Looks like the optimiser has a hard time with both of these instances (TLS check on the load and subsequent save vs. excessive register spills). Turns out the perf is about even though, with the implemented version here just nudging it out (but within the noise).
