The purpose of this patch is to find out more about the "shape" of
the constraints in our benchmarks. In particular, we would like to
determine whether aggregation and negation, together, appear in
recursive rules.

This patch adds an instruction to the datalog interpreter and
constructs a new AST node for min aggregation functions.
The compiler is currently still work in progress and depends on
changes made to the handling of simple joins and the preprocessor.
