The semantics of division by zero have changed from SMT 2.5 to SMT 2.6.

Allow CDHashMaps for objects without default constructors (#1092)

Add mkZero, mkOne and mkUmulo to bv utils. (#1200)
This adds several utility functions for the theory BV. Function mkUmulo encodes an unsigned multiplication overflow detection operation, which we need for CBQI BV. In the future, we will introduce a Umulo node kind (and a corresponding bit-blasting strategy based on the encoding implemented in mkUmulo).
