Before this PR, we relied strictly on crate dependency information from the extractor when resolving paths to crates. However, for whatever reason, this information may sometimes be incomplete, so in this PR we relax this condition and allow for a path to resolve to any crate in the DB, as long as the name of that crate does not conflict with the name of a known dependency.
In order to reduce path resolution inconsistencies, this PR also adds a step to make resolution of qualified paths like
q::pconsistent; of all the candidate resolution targets ofq, only chose the one(s) that are consistent with whatq::pmay resolve to.DCA looks great:
Percentage of calls with call targetincreases from 61.52 to 62.44, at only a marginal slowdown.
