Since https://reviews.llvm.org/rG93d08acaacec951dbb302f77eeae51974985b6b2
(https://reviews.llvm.org/D99551), several test CUDA regression tests are
failing with and "kernel image is invalid error".

First buildbot occurrence at http://meinersbur.de:8011/#/builders/1/builds/496

Example error message:
