Teach overload resolution to prefer user-defined conversion via a
lambda closure type's function pointer conversion over user-defined
conversion via a lambda closure type's block pointer conversion,
always. This is a preference for more-standard code (since blocks
are an extension)  and a nod to efficiency, since function pointers
don't require any memory management. Fixes PR12063.
