This translates the triple to a clang-defined enum... so strictly speaking no, that isn't possible.

Can you elaborate on the context where the backend needs this? I suspect in the backend we need a similar but not quite the same utility. Specifically, I think we need to translate the environment value to an unsigned integer. For all cases where an enum makes sense we should be using the Environment value in the backend.
