Prototype for the tail campaign (output unchanged, checked on 4nwv --mode scale --no-gpu: same .hkl, same
.mtz data):
- rsm/s and rsm/m TIMING sub-marks for each correction surface, the disposition and each stage of
MergeAndStats (the pieces the tail is spent in had no marks of their own).
- RefineDecay takes the terms MeasureRadiationDamageB just built (nothing between them changes corr)
instead of building them again, and evaluates its decay factor once per term where it used it twice.
- The merge's per-group and per-full scratch (MergeFields, FullsStaging, the accumulators, the R_meas sums
and their staging, the ISa scatter) default-initialised: each is written in full before it is read, and
std::vector zeroed - and faulted in - gigabytes of it on one thread per P1 merge.
