Make the SValBuilder capable to simplify existing SVals based on a newly added constraints when evaluating a BinOp. Before this patch, we called `simplify` only in some edge cases. However, we can and should investigate the constraints in all cases. Differential Revision: https://reviews.llvm.org/D113753
