    libstdc++: Use 'inline' consistently in std::exception_ptr [PR 97729]
    
    With PR c++/67453 fixed we can rely on the 'used' attribute to emit
    inline constructors and destructors in libsupc++/eh_ptr.cc. This means
    we don't need to suppress the 'inline' keyword on them in that file, and
    don't need to force 'always_inline' on them in other files.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/97729
            * libsupc++/exception_ptr.h (exception_ptr::exception_ptr())
            (exception_ptr::exception_ptr(const exception_ptr&))
            (exception_ptr::~exception_ptr()): Remove 'always_inline'
            attributes. Use 'inline' unconditionally.
