After r269667 which introduced joust_maybe_elide_copy, in C++17 we can elide
a constructor if it uses a conversion function that returns a prvalue, and
use the conversion function in its stead.
This eliding means that if we have a candidate that previously didn't have
->second_conv, it can have it after the elision. This confused the
-Wconversion warning because it was assuming that if cand1->second_conv is
non-null, so is cand2->second_conv. Here cand1->second_conv was non-null
but cand2->second_conv remained null, so it crashed in compare_ics.
I checked with clang that both compilers call A::operator B() in C++17 and
B::B(A const &) otherwise.

Defaulting the copy constructor on its first declaration made it change
