As new methods as been added to the slice type. I propose the add of these new methods too.
These iterators seems to be really useful to llvm and its optimizations.

Here is the tracking issue for exact_chunks/_mut; slice chunks with exact size.

(I labelled this parity-std::iter, but that's really std::slice -- maybe we need to use more labels...)

That addition sounds fine to me, but I'd prefer to wait for it to stabilize in std before we mimic it.

This is stable now. It would be awesome to see Rayon gain this feature. If help is needed, I'm willing to do the leg work.

Might also be interesting to have the rchunks_* iterators available from rayon in addition to this to have more API-equivalence between std and rayon

Follow-up PR from #510. `chunks_exact` (and its mutable counterpart) are not yet implemented on `ParallelIterator`, only `ParallelSlice`.
