[lld] r268551 - Handle errors on file opening as soft error.

New Revision: 268551

URL: http://llvm.org/viewvc/llvm-project?rev=268551&view=rev
Log:
Handle errors on file opening as soft error.

Also improves the error message. Previously it would just print out
the cause (e.g. "permission denied"). Now it prints out something like
"--reproduce: failed to open foo.cpio: permission denied".
