1208cc1611 [NFCI] SCEV: promote ScalarEvolutionDivision into an publicly usable class 
This makes it usable from outside of SCEV,
while previously it was internal to the ScalarEvolution.cpp

In particular, i want to use it in an WIP alloca promotion helper pass,
to analyze if some SCEV is a multiple of some other SCEV.
