libstdc++: Use deducing this in range adaptors even in C++20 [PR111550]
Use deducing this to implement perfect forwarding even in C++20 mode
by using the _GLIBCXX_EXPLICIT_THIS_PARAMETER internal FTM instead of
the standard __cpp_explicit_this_parameter. This fixes the original
testcase from this PR even in C++20 mode.
PR libstdc++/111550
libstdc++-v3/ChangeLog:
* include/std/ranges (views::__adaptor::_Partial::operator())
[_GLIBCXX_EXPLICIT_THIS_PARAMETER]: Also use deducing this
in C++20 mode when possible.
(views::__adaptor::_Pipe::Operator())
[_GLIBCXX_EXPLICIT_THIS_PARAMETER]: Likewise.
* testsuite/std/ranges/adaptors/take.cc (test07): New test.
