e454e96238 [varLib.builder] Implement building 32bit VarStore
The full optimizer in varLib.varStore still needs to be updated.
But this pretty much enables building 32bit VarStores, even if they
won't be fully optimal.

[varLib.builder] fix calculation of VarData.NumShorts
The problem was that `break` statement: we stopped searching for SHORT columns in each delta set after finding the first, but rows can contain more than one in any order.
