    libstdc++: Partially revert r11-9772-g6f8133689f4397 [PR105915]
    
    The r11-9772-g6f8133689f4397 backport made two changes, but only one was
    needed on the gcc-11 branch. The other should not have been backported,
    and causes errors with clang. This removes the unwanted part.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/105915
            * include/experimental/bits/fs_path.h (path::begin, path::end):
            Remove noexcept from declarations.
    
    (cherry picked from commit 60c84707034f025de3c8821cc5d6f27ff59143b0)
