...when such an operation is done on an object during con-/destruction.

This adds a test case to compiler-rt/test/ubsan/TestCases/TypeCheck/vptr.cpp that, unlike the existing test cases there, wants to detect multiple UBSan warnings in one go.  Therefore, that file had to be changed from globally using -fno-sanitize-recover to individually using halt_on_error only where appropriate.
