Implement evaluation for integers and bitvectors #137

Closed ryandancy closed 3 months ago

This expands Evaluator and DefinitionJit to evaluate integers, bitvectors, and builtin functions of the two. BvSignedRem and BvSignedMod aren't yet implemented since I wasn't sure what the difference between them is.

On 4-bit-adder.als, the evaluator reduces the time on my machine from ~6s to ~2s!

Looks good to me. I will leave @otzzila to look at the bit vector code. Interesting bug in the typechecker for sorts.
