libstdc++: Fix std::lexicographic_compare for unsigned char (PR 93972)
The new 25_algorithms/lexicographical_compare/93972.cc test fails on
targets where char is unsigned, revealing an existing regression with
the std::__memcmp helper that had gone unnoticed in
std::lexicographical_compare. When comparing char and unsigned char, the
memcmp optimisation is enabled, but the new std::__memcmp function fails
to compile for mismatched types.
PR libstdc++/93972
* include/bits/stl_algobase.h (__memcmp): Allow pointer types to
differ.
* testsuite/25_algorithms/lexicographical_compare/uchar.cc: New test.
