libstdc++: Use deducing this in std::not_fn when available [PR111327]
Implement the perfect forwarding required by std::not_fn using deducing
this when available, instead of needing 8 operator() overloads. This
also fixes Jiang An's test from this PR which would be messy to fix in
the old implementation.
PR libstdc++/111327
libstdc++-v3/ChangeLog:
* include/std/functional (_Not_fn::operator())
[_GLIBCXX_EXPLICIT_THIS_PARAMETER]: Define as a single
overload using deducing this.
* testsuite/20_util/function_objects/not_fn/111327.cc: Extend test.
