PR c++/86521 - C++17 copy elision in initialization by constructor.
This is an overlooked case in C++17 mandatory copy elision: We want overload
resolution to reflect that initializing an object from a prvalue does not
involve a copy or move constructor even when [over.match.ctor] says that
only constructors are candidates. Here I implement that by looking through
the copy/move constructor in joust.
* call.c (joust_maybe_elide_copy): New.
(joust): Call it.
