A substantial reorganisation of G4Transportation::AlongStepGPIL
to use values already in cache, reduce the number of branches, and
use extra local variables for track properties to avoid indirections.
The method is one of the heaviest in many types of simulation workloads.
Profiling identified a persistent reduction in misses of instruction-TLB
