This patch fixes some issues for the IteratorPastEnd checkers. There are basically two main issues this patch targets: one is the handling of assignments between iterators, the other one is correct handling of the +, +=, - and -= operators of random-access iterators. The handling of these operators also checks the sign of the argument, e.g. a negative number for + or += is handled as decrementation.
