    libstdc++: Fix typo in __size_to_integer(__GLIBCXX_TYPE_INT_N_3)
    
    The overload taking a signed type was returning unsigned and the
    overload taking an unsigned type was returning signed.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/stl_algobase.h (__size_to_integer): Move
            misplaced unsigned keyword on __size_to_integer overloads for
            __GLIBCXX_TYPE_INT_N_3 integer type.
    
    (cherry picked from commit 106591f79a3beaed226400fbdc568e95229dc936)
