DMC densities have incorrect weight (CPU code) #934

Per the report in #925 , the weight in the first block of the DMC AoS code is incorrect. This is a definite bug and needs to be fixed in AoS and SoA. A similar fix may be needed in the CUDA code, but an additional bug is likely present there.

I wonder if this is related to the remaining first step weights issue in #789. See the last "Trace of trial energy" plot there. The spikes right at the beginning of each DMC could relate to improper handling of the weights as is seen in the density estimator.
