Since LLVM r326341, default EmulatedTLS mode is decided in backend according to target triple. Any front-end should pass -f[no]-emulated-tls to backend and set up ExplicitEmulatedTLS only when the flags are used. Differential Revision: https://reviews.llvm.org/D43965 llvm-svn: 326499

// Android, Cygwin and OpenBSD use emutls by default.

// Clang should pass -femulated-tls or -fno-emulated-tls to cc1 if they are used,

// and cc1 should set up EmulatedTLS and ExplicitEmulatedTLS to LLVM CodeGen.
