Summary:
This patch removes the constraint dropping when taint tracking is disabled.
It also voids the crash reported in D28953 by treating a SymSymExpr with non pointer symbols as an opaque expression.
Updated the regressions and verifying the big projects now; I'll update here when they're done.
Based on the discussion on the mailing list and the patches by @ddcc.
