New Revision: 256120

URL: http://llvm.org/viewvc/llvm-project?rev=256120&view=rev
Log:
Add AVR.td and AVRRegisterInfo.td

Summary:
This adds the core AVR TableGen file, along with the register descriptions.

Lines in AVR.td which require other TableGen files which haven't been committed
yet are commented out.

This is a fairly trivial patch, and should only require a quick review.

I kept the line width smaller than 80 columns, but there are a few exceptions
because I'm not sure how to split a string over several lines.
