Previously the inliner did a bit of a hack by adding ref edges for all new edges introduced by performing an inline before calling updateCGAndAnalysisManagerForPass(). This was because updateCGAndAnalysisManagerForPass() didn't handle new non-trivial call edges. This adds handling of non-trivial call edges to updateCGAndAnalysisManagerForPass(). The inliner called updateCGAndAnalysisManagerForFunctionPass() since it was handling adding newly introduced edges (so updateCGAndAnalysisManagerForPass() would only have to handle promotion), but now it needs to call updateCGAndAnalysisManagerForCGSCCPass() since updateCGAndAnalysisManagerForPass() is now handling the new call edges and function passes cannot add new edges. We follow the previous path of adding trivial ref edges then letting promotion handle changing the ref edges to call edges and the CGSCC updates. So this still does not allow adding call edges that result in an addition of a non-trivial ref edge. This is in preparation for better detecting devirtualization. Previously since the inliner itself would add ref edges, updateCGAndAnalysisManagerForPass() would think that promotion and thus devirtualization had happened after any sort of inlining.
