It might be nice to check the code size impact, but my guess is that this isn't really a huge amount of new code. Not sure how much it matters anyway in terms of whether this gets used...

Inline or it inlines itself good enough?

Well, it worked in the microbenchmarks at least. With mir inlining, the cross-crate auto-inlining which was recently added and std being compiled with 1CGU that's probably enough.
If perf shows regressions I'll reconsider.
