UV overlap calculation makes baking stall + unresponsive Editor on asset refresh due to large mesh

Global Illumination

-

Steps to repro:

1. Open the repro project from the link below;
2. Open 'Bedroom_modelling' scene;
3. Drag 'Bedroom_Lighting' scene to the Hierarchy;
4. Double-click on 'Bedroom_Lighting' scene in the Hierarchy;
5. In the Lighting settings window press Generate Lighting button.

Expected result:
The lighting bakes as expected.

Actual result:
Baking stalls. Editor stalls and cannot closed without killing the Unity process.

Notes:
- Reproducible in 2019.1.0a11, 2018.3.0f1, 2018.2.0f19;
- Reproducible on Windows and OSX;
- Reproducible for either CPU PLM, GPU PLM or Enlighten baking backends;
- Disabling mesh optimization for the culprit mesh doesn't solve the issue;
- Auto Generating Lightmap UVs for the culprit mesh freezes Editor.

    Resolution Note:

    Not quite sure whether the mesh is broken, or the algorithm fails in this particular case. Given enough time I assume the bake would finish.
