Add an empty shell of llvm-rc.

This starts the development on one of MS Visual Studio binutils,
Resource Converter. The tool compiles resource scripts (.rc)
into binary resource files (.res).

The current implementation does nothing but parse the command
line arguments. It is going to be extended in the future.
