Fix a bug in Dialyzer related to call-site analysis
Dialyzer's "dataflow" module is using information from the callgraph to
determine which functions may be called at a particular call-site. Unfortunately
this information can include functions that are certainly not among the possible
choices. We don't want to emit warnings in such cases, so a "reasonable"
compromise is to stay silent if there are many possible funs and at least one of
them can succeed.
Bug reported by Dan Gudmundsson, test shrunk down by Magnus Lång.
