SubtargetFeature.h is currently part of MC while it doesn't depend on anything in MC. Since some LLVM components might have the need to work with target features without necessarily needing MC, it might be worthwhile to move SubtargetFeature.h to a different location. This will reduce the dependencies of said components. Note that I choose TargetParser as the destination because that's where Triple lives and SubtargetFeatures feels related to that. This issues came up during a JITLink review (D149522). JITLink would like to avoid a dependency on MC while still needing to store target features.
