Thanks for letting me know.  Now that your PR #122320 has landed, I've updated this PR to use it.

I see that `llvm::omp::getDeviceKernels` checks for the kernel calling convention but also still kernel in nvvm.annotations.  Should KernelInfo check for the latter as well?  My update only checks for the former.
