Add constant folding of all integer binops except exp
Summary:
A first cut of constant folding on expressions involving only binary operators on integers is now done.
* Representation of booleans is still wrong
* the star-star exponentiation operator is not yet implemented; it has odd codegen.
* div by zero semantics are not yet implemented
