@echristo - FYI, in case you have an opinion on target builtin feature checks.



================
Comment at: clang/include/clang/Basic/Builtins.h:263
+  ///    false if it is disabled.
+  bool isRequiredTargetFeaturesEnabled(
+      unsigned BuiltinID, const llvm::StringMap<bool> &TargetFetureMap) const;
----------------
I think we should boil it down to just `evaluateRequiredTargetFeatures(StringRef RequiredFeatures, ... TargetFeatureMap)`.



================
Comment at: clang/lib/Basic/BuiltinTargetFeatures.h:32
+/// pairs.
+class TargetFeatures {
+  struct FeatureListStatus {
----------------
I don't think it needs to be part of the public API. Feature check function operates on `llvm::StringMap<bool>` and does not need to know about this class, and the implementation of this class can be moved into `Builtins.cpp` where it's actually used.
