Title: Optimise NORMALIZE to DATASET

This optimisation regards transforming a number of
normalize(row, count, trans(COUNTER)) constructs into
dataset(count, trans(COUNTER)). Added DATASET
to the code that filters unused fields of a transform.

Tests added, on both compiler and regression suites.
All compiler changes were expected, no transform
bodies changed, only simplification from ROW+NORMALIZE
to DATASET.
