FWIW, with just about any modern-ish compiler just using "inline" doesn't
actually force inlining, it just changes the cost model to make it more
likely.

I'm not opposed. I'd however at least add a comment explaining why this is
being used. Arguably it doesn't make sense to add it to *_create(), as without
that there really isn't a point in having a simplehash instantiation. Might
make it slightly easier to notice obsoleted uses of simplehash.
