Libomptarget uses some shared variables to track certain internal stated in the runtime. This causes problems when we have code that contains no OpenMP kernels. These variables are normally initialized upon kernel entry, but if there are no kernels we will see no initialization. Currently we load the runtime into each source file when not running in LTO mode, so these variables will be erroneously considered undefined or dead and removed, causing miscompiles. This patch temporarily works around the most obvious case, but others still exhibit this problem. We will need to fix this more soundly later. Fixes llvm#54208.
