Evan Cheng d8e27a584e Switch SubtargetFeatures from std::string to StringRef. 
llvm-svn: 134219

Evan Cheng fe6e405e8c Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to 
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!
