Title: Optimise NORMALIZE to DATASET - Take 2

This optimisation regards transforming a number of
normalize(row, count, trans(COUNTER)) constructs into
dataset(count, trans(COUNTER)). The code is correct
for some, not all, studied cases, while others
break compilation.

It compiles the long list of examples and the output is identical, while the C++ is heavily trimmed.

I'm still investigating every difference in the C++ side, but it seems it didn't affect the overall result of the queries. I'll add the ECL code to both ```ecl/regression``` and ```testing/ecl``` later, when I'm sure the results are correct.
