Reproduction steps:
1. Open the Superluminal profiler
2. Open the attached "repro_IN-40868.zip" project
3. Start profiling the "Unity.exe" process in the Superluminal profiler
4. Enter the Play Mode in the Unity Editor
5. After a few seconds, stop the Play Mode
6. Stop the profiling in the Superluminal profiler
7. Observe the profiling data
Expected result: no time is spent on Texture2D::UnshareTextureData during LoadRawTextureData, because TextureCreationFlags.DontUploadUponCreate is in use so the TextureData should not be referenced by the upload.
Actual result: the data upload is skipped, but Texture2D::UnshareTextureData still takes longer than expected (RefCount is not 1).
