Preliminary support for binops in if-discriminators
...
The BNF grammar is a bit more liberal than any successfully-compiled
schala program should be, in that it allows things like `if x < is
pattern`. It's okay if that parses successfully and then is an error at
typechecking.

I think I need to entirely change the types in the evaluator.
ReducedAST should only care about NewConstructor (which I gotta rename),
and the evaluator is the only place that an implementation of a
primitive constructed type should live (see Peyton-Jones implementing a
functional langauge p. 70)
