Works as expected --- (Base.arrayref)(false, xs, i) in @code_typed:
```
function update(xs, i)
    @inbounds xs[i] += 1
end
```

`@inbounds` ignored --- (Base.arrayref)(true, xs, i) in @code_typed:
```
@inbounds function update(xs, i)
    xs[i] += 1
end
```

`@simd` fails to vectorize --- (Base.arrayref)(true, xs, i) in @code_typed:
```
@inline function update(xs, i)
    xs[i] += 1
end
@inbounds @simd for i in eachindex(xs)
    update(xs, i)
end
