@erichkeane Apologies, I should have structured the commits differently so it's clear what the new changes are...

I added an `IsAddressOfOperand` parameter to `TreeTransform::TransformUnresolvedLookupExpr` and changed the conditions under which `Sema::BuildPossibleImplicitMemberExpr` is called to match those in `Sema::ActOnIdExpression`.
