This should not be necessary. Old bitcode is supposed to be forward compatible
and should be autoupgraded. You should not need to check that the runtime
version matches. The sticking point for AMDGPU specifically is I do not want to
guarantee compatibility for the legacy intrinsics still in use. They have
various problems, and some of them make it difficult to support auto upgrading
them. Going forward I would like to maintain compatibility with new properly
defined intrinsics.
