This makes it so that we no longer use a LUT (Look-Up Table): * The code is much simpler and easier to understand now. * Using a LUT means we rely on a warm cache. Relying on the cache like this results in inconsistent performance and in many cases codegen will be worse. Also as @topolarity once pointed out, in some cases while it seems like the code may branch, it actually doesn't: https://github.com/ziglang/zig/pull/11629#issuecomment-1213641429 * Other languages' standard libraries don't do this either. JFF I wanted to see what other languages codegen compared to us now: https://rust.godbolt.org/z/Te4ax9Edf, https://zig.godbolt.org/z/nTbYedWKv So we are pretty much on par or better than other languages now.
