[PATCH] D136315: [clang][Darwin] Try to guess the SDK root with xcrun when unspecified

[Caleb Zulawski via Phabricator via cfe-commits]

calebzulawski added a comment.

If `clang -target arm64-apple-ios -isysroot path/to/MacOSX.sdk` changes the target to `x86_64-apple-macos` to match the SDK, that would be very confusing behavior :) I'll have to investigate that function some more.
