Mark, Lookup for a particular conversion operator looped unnecessarily, but more importantly lookup_conversions, which gathers all the visible conversions would only DTRT in singly inherited hierarchies.

This is one of those cases where you're sort-of amazed people didn't run into more serious problems.

This replacement does the set of parallel lookups that need to be done,
complete with the hiding that happens with virtual bases.  Whilst there
I took advantage of TYPE_HAS_CONVERSION, to avoid unnecessary walking.

booted & tested on i686-pc-linux-gnu, ok?

Yes, thanks.
