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.

[rnk]

Minor comment, looks good otherwise.

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.
