I don't think this is the right design for this feature: Forcing essentially all targets to add the same subtarget feature and associated logic is not good.

Instead, please add this to include/llvm/Target/TargetOptions.h, and add default handling in lib/Target/TargetMachine.cpp (command-line options, function attributes, etc.).
