[PATCH] D15746: Normalize the features string in SubtargetFeatures::getFeatureBits

[Eric Christopher via llvm-commits]

I mean basically not allowing the use that you're trying for there. Any duplications or changes aren't going to matter.

Also, FWIW, any subtarget feature that isn't isolated really isn't good. I.e. you should have to explicitly turn on both fp-armv8 and fullfp16 if you want both enabled.
