  Log Message:
  -----------
  [AssumeBundles] add cannonicalisation to the assume builder

Summary:
this reduces significantly the number of assumes generated without aftecting too much
the information that is preserved. this improves the compile-time cost
of enable-knowledge-retention significantly.
