Currently clang does not emit device template variables instantiated only in host functions, however, nvcc is able to do that: https://godbolt.org/z/fneEfferY This patch fixes this issue by refactoring and extending the existing mechanism for emitting static device var ODR-used by host only. Basically clang records device variables ODR-used by host code and force them to be emitted in device compilation. The existing mechanism makes sure these device variables ODR-used by host code are added to llvm.compiler-used, therefore they are guaranteed not to be deleted. It also fixes non-ODR-use of static device variable by host code causing static device variable to be emitted and registered, which should not.
