Diff 3 simplified the clang front-end and driver changes:

- Only -femulated-tls and -fno-emulated-tls flags are added. Default is -fno-emulated-tls mode.

- Unit tests are modified to check:
  - C uninitialized global variables are common, but uninitialized thread local variables are not.
  - The -femulated-tls and -fno-emulated-tls flags are passed from clang to cc1.
