libstdc++: Implement P2968R2 "Making std::ignore a first-class object"
This was recently approved for C++26, but we can apply the changes for
all modes back to C++11. There's no reason not to make the assignment
usable in constant expressions for C++11 mode, and noexcept for all
modes.
Move the definitions to <bits/utility.h> so they're available in
<utility> as well as <tuple>.
libstdc++-v3/ChangeLog:
* include/bits/utility.h (_Swallow_assign): Make assignment
constexpr for C++11 as well, and add noexcept.
* include/std/tuple (_Swallow_assign, ignore): Move to
bits/utility.h.
* testsuite/20_util/headers/utility/ignore.cc: New test.
