Different `tau` array in qr

The array tau that's returned looks different from what Julia returns. Why are they different?

@ranjanan I think tau is implementation dependent.

Yes, this is a placeholder for me to check how the arrayfire and Julia implementations are different.

I am just saying tau is never used by itself so the values shouldn't matter. It is always used along with the other outputs from QR.

That it's different is not to me as important as whether it's internally consistent.
