Eliminate partial operators in sygus grammar normalization (#2323)
This corrects a bug that was introduced in #2266 (the hack removed there was necessary).
This ensures that we handle operators like bvudiv, bvsdiv, bvurem, div, rem, / properly in sygus.
This also enables total semantics for BV div-by-zero for sygus.
