[PATCH] D25845: [CUDA] Ignore implicit target attributes during function template instantiation.

- Instead of relying on the first attribute we find, check all matching ones.
- Specializations inherit their target attributes from their base template only. Their effective target always matches that of the template and is no longer affected by whether specialization differens from template in its constexpr-ness.
