Title: SI-6335 More precise location of the implicit class synthetic method.

One approach would be to disallow an implicit class in a template
that already has a member with the same name.

But this commit doesn't do this; instead it uses `isSynthetic` to
find the synthesized implicit conversion method from the potentially
overloaded alternatives.
