> Iterating slices instead of indexes seems to improve performance of non-simd
> arithmetic operations.
> This adds a new method raw_values_slice to PrimitiveArray (so named to pun
> off of the raw_values function which returns a pointer). A few of the
> functions in PrimitiveArray rely on the caller for safety guarantees
> (bounds-checks for value_slice, value), so should probably be unsafe? But
> they are used widely, so I thought it simpler to start by adding a safer
> alternative...
