Chris Lattner 46ca76f6bb fix a crash building SPASS by tolerating a callsite that doesn't exist
in the callgraph, see the big comment at the top of the testcase.

; This test was failing because the inliner would inline @list_DeleteElement
; into @list_DeleteDuplicates and then into @inf_GetBackwardPartnerLits,
; turning the indirect call into a direct one. This allowed instcombine to see
; the bitcast and eliminate it, deleting the original call and introducing
; another one. This crashed the inliner because the new call was not in the
; callgraph.
