[PATCH] D10524: Clang/driver: emulated TLS mode.

How does GCC do expose this model? Do they support `__attribute__((tls_model("emulated")))`, or is it a backend option like Joerg is suggesting?

If we go the backend option route, it doesn't have to be specific to Android, we can have some target predicate that can change in the future like `useGCCEmulatedTLS()`.

You can avoid duplicating the CHECK lines by giving FileCheck multiple prefixes:
  | FileCheck --check-prefix=COMMON --check-prefix=EMU %s
