[Discuss-gnuradio] Volk in place

I would like to use volk functions where the input memory is also used to store the output. e.g. the numerator given to volk_divide is also the result of the division:
```
volk_32fc_magnitude_squared_32f_a(out, in0, N);
volk_32f_x2_divide_32f_a(out, out, in1, N);
```
I have not seen any official documentation indicating that in place ops are allowed. Of course, maybe I missed something.

A quick search brings up a few references; the most recent discussion was under the subject "VOLK division between complexes" where Marcus Müller suggested doing a `volk_32fc_magnitude_squared_32f` in place. In another discussion, under the subject "[VOLK] Test-case behaviour," Martin Braun indicates that in place ops should work and documentation would be considered.

I'm mostly curious to know if this would be platform/instruction specific or if the in place ops should be guaranteed to work for any given kernel. I'm about to test to see if in place ops works for my use case now. I'll report back.
