clang-p2996/clang/test/OpenMP/target_offload_mandatory_codegen.cpp
dhruvachak b5d02bbd0d [OpenMP] Increment kernel args version, used by runtime for detecting dyn_ptr. (#85363) 
A kernel implicit parameter (dyn_ptr) was introduced some time back.
This patch increments the kernel args version for a compiler supporting
dyn_ptr. The version will be used by the runtime to determine whether
the implicit parameter is generated by the compiler. The versioning is
required to support use cases where code generated by an older compiler
is linked with a newer runtime.

If approved, this patch should be backported to release 18.
