COFF: Infer entry symbol name if /entry is not given. `main` is not the only main function in Windows. You can choose one from these four -- {w,}{WinMain,main}. There are four different entry point functions for them, {w,}{WinMain,main}CRTStartup, respectively. The linker needs to choose the right one depending on which `main` function is defined. llvm-svn: 238667

Use error() instead of warn() to report undefined symbols. I believe the reason why we used warn() instead of error() to report undefined symbols is because the older implementation of error() exitted immediately. Here, we want to find as many undefined symbols as we can, so I chose to use warn() instead of error(). Now error() does not exit immediately, so it doesn't make sense to keep them as warnings.
