Add support for SuiteB and ECC primitives

[weaversa]

For my needs, I want to do a proof using w4_unint_yices and uninterpret these functions, but I can't currently load a Cryptol file that references these primitives.

You have encountered a bug in cryptol-saw-core's implementation.

It shouldn't be too much work to add a stub for this primitive that can be treated as an uninterpreted function.

I think a quick and simple stub could be for saw to simply define these as undefined.

[brianhuffman]

Yes, I'll just stub these out as undefined for now. Also I should extend the cryptol-test-suite to translate all of Cryptol's built-in modules, instead of just translating Cryptol.cry as it does now.
