Replaced MSL with Iris, rebuilt VeriC and Floyd on top of it.

Per Robbert, this hugely improves the performance of setoid rewriting.
This avoids adding some universe constraints.
Calling atomic specs should work better now.
Further improvement probably needs to target either `autorewrite with norm` (which might be unavoidably slow because of setoid rewrite), or `auto` (which is slow because of `Hint Extern`s in Iris).
also attempting to set up CI
This is a PR-specific hack and should be replaced once Iris is a standard dependency.

@andrew-appel I'm now working on getting this to pass the CI -- it currently works only for 8.17 and 64-bit mode. Which Coq versions and bitsizes does it need to pass? (I'd prefer not to have to support 8.16, if that makes sense.)
