This patch makes LLDB use the Event Viewer on Windows (equivalent of system logging on Darwin) rather than piping to the standard output (which was deactivated in ca0a524.
…154424) `std::wstring AnsiToUtf16(const std::string &ansi)` is a reimplementation of `llvm::sys::windows::UTF8ToUTF16`. This patch removes `AnsiToUtf16` and its usages entirely.
…vm#156474) In llvm#150213 we made use of the Event Viewer on Windows (equivalent of system logging on Darwin) rather than piping to the standard output. This turned out to be too verbose in practice, as the Event Viewer is developer oriented and not user oriented. This patch swaps the use of `ReportEventW` for `OutputDebugStringA`, allowing to use tools such as `DebugView` to record logs when we are interested in receiving them, rather than continuously writing to the buffer.
