Summary: Error handling in liblldCore and the Darwin toolchain prints to an output stream. A TODO in the project explained that a diagnostics interface resembling Clang's should be added. For now, the simple diagnostics interface defined in liblldCommon seems like an improvement. It prints colors when they're available, uses locks for thread-safety, and abstracts away the `"error: "` and newline literal strings that litter the Darwin toolchain code. To use the liblldCommon error handler, a link dependency is added to the liblldDriver library. Test Plan: 1. check-lld 2. Invoke `ld64.lld -r` in a terminal that supports color output. Confirm that "ld64.lld: error: -arch not specified and could not be inferred" is output, and that the "error:" is colored red!
