Adam Balogh afcb77cc88 [Analyzer] Fix for incorrect use of container and iterator checkers 
Iterator checkers (and planned container checkers) need the option
aggressive-binary-operation-simplification to be enabled. Without this
option they may cause assertions. To prevent such misuse, this patch adds
a preventive check which issues a warning and denies the registartion of
the checker if this option is disabled.

Devin Coughlin 9a2c14a73a [analyzer] Fix unreachable creating PathDiagnosticLocation with widen-loops=true 
In the original design of the analyzer, it was assumed that a BlockEntrance
doesn't create a new binding on the Store, but this assumption isn't true when
'widen-loops' is set to true. Fix this by finding an appropriate location
BlockEntrace program points.
