libstdc++: Disable volatile-qualified std::bind for C++20
LWG 2487 added a precondition to std::bind for C++17, making
volatile-qualified uses undefined. We still support it, but with a
deprecated warning.
P1065R2 made it explicitly ill-formed for C++20, so we should no longer
accept it as deprecated. This implements that change.
libstdc++-v3/ChangeLog:
* doc/xml/manual/evolution.xml: Document std::bind API
changes.
* doc/xml/manual/intro.xml: Document LWG 2487 status.
* doc/xml/manual/using.xml: Clarify default value of
_GLIBCXX_USE_DEPRECATED.
* doc/html/*: Regenerate.
* include/std/functional (_Bind::operator()(Args&&...) volatile)
(_Bind::operator()(Args&&...) const volatile)
(_Bind_result::operator()(Args&&...) volatile)
(_Bind_result::operator()(Args&&...) const volatile): Replace
with deleted overload for C++20 and later.
* testsuite/20_util/bind/cv_quals.cc: Check for deprecated
warnings in C++17.
* testsuite/20_util/bind/cv_quals_2.cc: Likewise, and check for
ill-formed in C++20.
