111a462d16 C++: Recover some of the good results we lost 
My recent changes to suppress FPs in `ReturnStackAllocatedMemory.ql`
caused us to lose all results where there was a `Conversion` at the
initial address escape. We cannot handle conversions in general, but
this commit restores the good results for the trivial types of
conversion that we can handle.
