A typo in r15-4473-g3abe751ea86e34 made it ill-formed to use
std::uninitialized_fill with iterators that aren't pointers (or pointers
wrapped in our __normal_iterator) if the value type is a narrow
character type.
libstdc++-v3/ChangeLog:
PR libstdc++/120931
* include/bits/stl_uninitialized.h (__uninitialized_fill<true>):
Fix typo resulting in call to __do_uninit_copy instead of
__do_uninit_fill.
* testsuite/20_util/specialized_algorithms/uninitialized_fill/120931.cc:
New test.

Tested powerpc64le-linux. Pushed to trunk. Backport to gcc-15 to follow.
