[PATCH] D47799: [COFF] add /errorrepro to save reproducer on error

I am investigating https://bugs.chromium.org/p/chromium/issues/detail?id=786127, which is a failure that does not reproduce reliably. I could use /linkrepro to save all link inputs always, but that would use up a lot of disk space. Running the command again with /linkrepro will almost certainly not reproduce the failure. Having a way to only save the reproducer when an error occurs would help here, and also seems a generally useful feature to have.
