[PATCH] D44336: Implement --cref.

[Rui Ueyama via Phabricator via llvm-commits]

Herald added subscribers: arichardson, emaste.

This is an option to print out a table of symbols and filenames.
The output format of this option is the same as GNU, so that it can be
processed by the same scripts as before after migrating from GNU to lld.

This option is mildly useful; we can live without it. But it is pretty
convenient sometimes, and it can be implemented in 50 lines of code, so
I think lld should support this option.
