Brian Gesiak b9f7f4b87c [Darwin] Use errorHandler from liblldCommon 
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!
