rust-index: improve phase computation speed

While less memory efficient, using an array is *much* faster than using a
HashMap, especially with the default hasher. It even makes the code simpler,
so I'm not really sure what I was thinking in the first place, maybe it's more
obvious now.

This fix a significant performance regression when using the rust version of the
code. (however, the C code still outperform rust on this operation)
