Test failure fixed; removing that override was a little reckless. I'll do a another small evaluation to make sure this doesn't mess with performance (but I think it shouldn't). |

Small evaluation on ace and node shows no major performance impact, so I consider this ready to merge (but would of course be happy to do a more extensive evaluation if desired). |

Fixes https://discuss.lgtm.com/t/false-positive-in-preact/1348.
The actual fix is in the first commit and involves a minor rearrangement so we don't assume
VarDef.getSource()is always defined (because it isn't).Once I had that in,
LocalFunctionstarted acting up with a very expensiveantijoin_rhs. I have no idea why that suddenly became a problem, but the second commit refactors things to fix it.Overall, there is no performance overhead (in fact, the second commit gives us a speedup on some projects), and results are unchanged except for the reported FP in preact, which I'm adding to our default benchmark suite. Given the fact that I wasn't able to find a single other change in results, I think we can skip a change note.
