We don't require users to type out the full context of a function, for symbol name matches. Instead, we extract the incoming path's base name, look up all the symbols with that base name, and then compare the rest of the context that the user provided to make sure it matches. However, we do this comparison using just a strstr. So for instance:
break set -n foo::bar
will match not only "a::foo::bar" but "notherfoo::bar". The former is pretty clearly the user's intent, but I don't think the latter is, and results in breakpoints picking up too many matches.
This change adds a Language::DemangledNameContainsPath API which can do a language aware match against the path provided. If the language doesn't provide this we fall back to the strstr (though that's changed to StringRef::contains in the patch).
