Mehdi Amini c68b6482c1 Add an internalization step to the ThinLTOCodeGenerator
Keeping as much as possible internal/private is
known to help the optimizer. Let's try to benefit from
this in ThinLTO.
Note: this is early work, but is enough to build clang (and
all the LLVM tools). I still need to write some lit-tests...
