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

Are those failures on Linux? I only developed this change on macOS, but the automated tests passed...

Admittedly I'm not sure what should happen when building for macOS from Linux (is there any use case where that works and does anything useful? I'm not sure).  I was under the impression that the Darwin driver applied to Darwin hosts, not targets, but if that's not true, it would attempt to run xcrun. If xcrun isn't found, no error occurs but the sysroot remains unset.
