Write to stdout if `-` is given as output file
If `-o -` or `--emit KIND=-` is provided, output will be written to stdout instead. Binary output (`obj`, `llvm-bc`, `link` and `metadata`) being written this way will result in an error unless stdout is not a tty. Multiple output types going to stdout will trigger an error too, as they will all be mixded together.
