Achieve successful simulation of 100% MSL 3.2.3 models with NF

[Francesco Casella]

We have a strategic goal of simulating 100% of the MSL models with annotation(experiment(StopTime)). This involves some remaining issues with the NF, but also some back-end/runtime issues, that were already present with the old FE and are not solved by the new one.

At this point in time, there are 27 models that do not simulate successfully in the MSL 3.2.3 release candidate. I have already identified the following open issues:

• New front-end: #5015, #5240, #5284
• Back-end: #5170, #5235

I will update the list as I identify the root cause of the remaining failing models.

I think it would be nice if we could fix them before we release 1.14.0. That would be a clearly recognizable milestone for that release.
