done on moving this handling to a helper. I made ICallAnalysis a private member, however it is initialized by another helper at the beginning of applyImport, since it isn't needed in other cases that use this class (e.g. fullLTO). I didn't move ICallAnalysisMap (now ICallAnalysisInfo) since that is a per-function data structure.
