c++: tweak c++17 ctor/conversion tiebreaker [DR2327]
In discussion of this issue CWG decided that the change of behavior on
well-formed code like overload-conv-4.C is undesirable. In further
discussion of possible resolutions, we discovered that we can avoid that
change while still getting the desired behavior on overload-conv-3.C by
making this a tiebreaker after comparing conversions, rather than before.
This also simplifies the implementation.
The issue resolution has not yet been finalized, but this seems like a clear
improvement.
