pcc@  Originally I tried to make the change in ModuleSummaryAnalysis.cpp, but  it turns out that this is not allowed in LLVM:  I am not supposed to make changes to the IR in the Analysis layer of LLVM.  I need to find some place in the Transform layer to make the change.  Hence my first guess as to a location: GlobalOpt.cpp.  I would be happy to make the change in some other location instead, but it must be someplace in the Transform layer.
