There was a problem hiding this comment.
This is needed because otherwise incremental tests crash with the new analyzer (I added couple incremental tests) with something like 'BuildManager' doesn't have attribute 'semantic_analyzer'.

Fixes #6413
In my original PR I missed the fact that "broken" named tuples (those where variable name and named tuple name are different) are stored under both names (one to actually access it, and other for (de)serialization).
I also extend the semantic analyzer API, and clean-up/clarify the symbol adding logic a bit.
