Nicholas Nethercote 936a8232df Change signature of target_features_cfg. ... Currently it is called twice, once with `allow_unstable` set to true and once with it set to false. This results in some duplicated work. Most notably, for the LLVM backend, `LLVMRustHasFeature` is called twice for every feature, and it's moderately slow. For very short running compilations on platforms with many features (e.g. a `check` build of hello-world on x86) this is a significant fraction of runtime. This commit changes `target_features_cfg` so it is only called once, and it now returns a pair of feature sets. This halves the number of `LLVMRustHasFeature` calls.		2025-03-05 09:49:17 +11:00
