querying for analysis results on a function declaration rather than a definition. The only reason this worked previously is by chance -- because the way we got alias analysis results with the legacy PM, we happened to not compute a dominator tree and so we happened to not hit an assert even though it didn't make any real sense. Now we bail out before trying to compute alias analysis so that we don't hit these asserts. llvm-svn: 307625
