OK, so the assembly has to be tested because there's no way to get an
object file to dwarfdump during LLVM testing (due to the lack of ptxas)
But is it possible to test something less than every line of the assembly
output? What features are you interested in checking for (assuming that
LLVM's dwarf output is already fairly well tested)?

The problem is that ддс is unable to generate an object file for NVPTX target, it requires an external tool called ptxas which is part of the cuda toolchain.
