This ensures that the entry function is never elided due to inlining, even with `inline(always)`. Fixes rust-lang#47783. There were a couple of possible ways of addressing this issue; I simply picked the one that seemed most direct. A warning could be appropriate, but considering using inlining hints in other places it doesn't apply also throws no warnings, and it seems like an edge case anyway, I haven't added one for now.
