By inheriting from
ai_basetyou can create different kinds of abstract interpreter. At the moment theai_recursive_interproceduraltis the least general common ancestor for all of the interpreters. This does interprocedural analysis by recursion. In this PR I add an alternative which does function-local analysis. This is of general interest in making fast analyses but was particularly inspired by #6528 and @tautschnig 's work on thelocal_*analysis functionality.To come, support in
goto-analyzerand test cases.
