Add RequiredPass into list of lower level passes required by pass P. RequiredPass is run on the fly by Pass Manager when P requests it through getAnalysis interface.

Add RequiredPass into list of lower level passes required by pass P. RequiredPass is run on the fly by Pass Manager when P requests it through getAnalysis interface. This should be handled by specific pass manager.
