Auto merge of #64600 - scottmcm:no-slice-tryfold-unroll, r=bluss
Remove manual unrolling from slice::Iter(Mut)::try_fold While this definitely helps sometimes (particularly for trivial closures), it's also a pessimization sometimes, so it's better to leave this to (hypothetical) future LLVM improvements instead of forcing this on everyone. I think it's better for the advice to be that sometimes you need to unroll manually than you sometimes need to not-unroll manually (like #64545). --- For context see https://github.com/rust-lang/rust/pull/64572#issuecomment-532961046
