c8a123b7dd Disable a few rule transformations 
For this prototype, we need to disable three rule transformations,
namely coi_filter, similarity_compressor, rule_inliner. But
disabling the inliner causes problems with the tracer in the
datalog interpreter. Since a new proprocessor is underway, we
skip the problematic trace outputs for now.

132f984d51 Add syntactical min checker 
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.

140fb7942d Add datalog infrastructure for min aggregation function 
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.
