Auto merge of #42436 - ollie27:win_spawn_name, r=alexcrichton
Always quote program name in Command::spawn on Windows [`CreateProcess`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425.aspx) will interpret args as part of the binary name if it doesn't find the binary using just the unquoted name. For example if `foo.exe` doesn't exist, `Command::new("foo").arg("bar").spawn()` will try to launch `foo bar.exe` which is clearly not desired.
