Enhancement: make the bool-to-bv pass more robust and targeted (#3021)
This pull request is an improvement to the bool-to-bv preprocessing pass. The existing pass is both too weak and too strong, depending on the circumstance. Throughout this description, "lower" refers to lowering a boolean to a bit-vector.
