Given an instruction I, the MustBeExecutedContextExplorer allows to easily traverse instructions that are guaranteed to be executed whenever I is. For now, these instruction have to be statically "after" I, in the same or different basic blocks. This patch also adds a pass which prints the must-be-executed-context for each instruction in a module. It is used to test the MustBeExecutedContextExplorer, for now on the examples given in the class comment of the MustBeExecutedIterator.
