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.

Adding the new enumerator forced a bunch more changes into this patch than I
would have liked. The -Wtautological-compare warning was extended to properly
check the new comparison operator, clang-format needed updating because it uses
precedence levels as weights for determining where to break lines (and several
operators increased their precedence levels with this change), thread-safety
analysis needed changes to build its own IL properly for the new operator.
All "real" semantic checking for this operator has been deferred to a future
patch. For now, we use the relational comparison rules and arbitrarily give
the builtin form of the operator a return type of 'void'.

Summary: SimpleConstraintManager is difficult to use, and makes assumptions about capabilities of the constraint manager. This patch refactors out those portions into a new RangedConstraintManager, and also fixes some issues with camel case, formatting, and confusing naming.
