(#Closes 2875) Implementation to handle elemental functions in wheres

[LonelyCat124]

Improves the implementation of wheres to do better with elemental functions. Its a relatively small change that should work out the box....

Ready for review assuming integration is ok @sergisiso @arporter

[LonelyCat124]

Integration passed successfully.

Thanks for this fix @LonelyCat124, as I mentioned in my in-line comments it is not obvious to me why this should work, but I suggest starting with my comments requesting additional tests as I will be ok with it if it is proven to work.

[LonelyCat124]

@sergisiso Comments should be addressed - had to reorder a couple of statments and add an additional test to directly test some code that is currently unreachable, but may be necessary to handle future improvements.

I will also rerun the integration tests as there are more impvoements here.

Previous branch had some deviation on nemo 5, will resubmit

[LonelyCat124]

Pushed the wrong branch to integration last night, set the right one going today.

[sergisiso]

Ah, the detail I has missing was that we don't support Imports or Unresolved anyway and therefore we don't have to worry about unknown 'elemental' attribute, it is much clearer now. I will wait until integration tests are done to finish the review.

[LonelyCat124]

Integration is now passing.

NEMOv5 CPU parallelisation was slower, but there were lots of people heavily using the machine that day and this is a threaded run, so it is expected that it was slower. But since this is one of our current targets, I want to re-run only this action when the machine is empty today or over the weekend.
