Add an empty shell of llvm-rc.

[mnbvmar]

Summary

This starts the development of llvm-rc, a platform-independent port of Microsoft's rc.exe tool. The current revision includes only command-line arguments parsing.

The shell is similar in its implementation to llvm-cvtres.

I don't think you need this.

[mnbvmar]

Typos fixed.

These look unused. Do we need them?

Indeed, these were taken from cvtres tool and are unnecessary here. I'm going to remove them (and reportError, too).

[mnbvmar]

Removed unnecessary error handling methods.
