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

One thing to throw into the mix: Apple's clang has a default sysroot configured, so with the default system compiler, there is no way to replicate this "build without a sysroot" scenario as far as I can tell.  For the system compiler, I believe this behavior is a strict improvement.

Looking at all of the errors, it looks like the common thread is that when a sysroot is present, the version in the target triple (e.g. `x86_64-apple-macos10`) isn't respected.  If this is true, I think this possibly uncovered an existing bug...
