Yes, sure, makes sense to re-use what we already computed. @Technici4n Any problems with merging this before #1088 ? |

During the calculation of the AtomicNonlocal forces, the projectors are recomputed for each element and k-point. There is no good reason to do that since they are already stored in the TermAtomicNonlocal.
This mostly impacts GPU performance, as relatively slow CPU loops over G + k vectors are avoided. This PR might collide with #1088.
