[Analyzer] Instead of recording comparisons in interator checkers do …
…an eager state split Currently iterator checkers record comparison of iterator positions and process them for keeping track the distance between them (e.g. whether a position is the same as the end position). However this makes some processing unnecessarily complex and it is not needed at all: we only need to keep track between the abstract symbols stored in these iterator positions. This patch changes this and opens the path to comparisons to the begin() and end() symbols between the container (e.g. size, emptiness) which are stored as symbols, not iterator positions. The functionality of the checker is unchanged. Differential Revision: https://reviews.llvm.org/D53701 llvm-svn: 358951
