Subject: [PATCH] Add frontend/bin/frontend_command.rb for development

For during development of Nullarihyon, use the command to generate Xcode build phase script.

```
$ ruby -I lib:bundle bin/frontend_command.rb check --analyzer=../build/driver/Debug/nullarihyon-core --resource-dir=../vendor/clang+llvm-3.8.0-x86_64-apple-darwin/lib/clang/3.8.0/
```

It generate command line with options converted to absolute path. Copy the output and paste it to Xcode.
