[PATCH] D81678: Introduce noundef attribute at call sites for stricter poison analysis

Added an across-the-board test with several different interesting cases. @rsmith, I'm not sure how to test things like VTables/VTTs, since afaik the way they would be exposed to function attributes would be if a struct is being passed by value. But in that case, we currently never emit noundef.
