Jakob Rath d3b5974448 shortcut in add_value 
otherwise, with literal x == a for constant a, we will create unnecessary value nodes.
(because slicing will propagate x := a to the solver, which calls add_value in turn)

Jakob Rath 2d0120c621 Merge some intermediate slices 
In particular, this ensure propagates of values to extracted variables.
(previously it could happen that x = y[h:l], y is assigned in the
solver, but x is not propagated; because only base slices have been
merged.)
