Adam Balogh 855d21a03a [Analyzer] Iterator Checkers: Replace UnknownVal in comparison result by a conjured value ...

Sometimes the return value of a comparison operator call is
`UnkownVal`. Since no assumptions can be made on `UnknownVal`,
this leeds to keeping impossible execution paths in the
exploded graph resulting in poor performance and false
positives. To overcome this we replace unknown results of
iterator comparisons by conjured symbols.
