      Description

      The vectorized aggregates code is sprinckled with checks of the primitive types (int, bigin, long, double, string etc), eg:

      VectorHashKeyWrapperBatch.compileKeyWrapperBatch
      VectorizedRowBatch.createObjectInspector
      VectorizationContext.mapObjectInspectors
      VectorizationContext.columnTypes
      VectorizationContext.allocateColumnVector
      more?

      This is unmaintainable. We need to centralize and abstract all these type checks into a single place.
