Emulated TLS is enabled by llc flag -emulated-tls, which is passed by clang driver. When llc is called explicitly or from other drivers like LTO, missing -emulated-tls flag would generate wrong TLS code for targets that supports only this mode. Now use useEmulatedTLS() instead of Options.EmulatedTLS to decide whether emulated TLS code should be generated. Unit tests are modified to run with and without the -emulated-tls flag.
