libstdc++: Fix ranges::copy_backward for a single memcpyable element [PR117121]
The result iterator needs to be decremented before writing to it.
Improve the PR 108846 tests for all of std::copy, std::copy_n,
std::copy_backward, and the std::ranges versions.
libstdc++-v3/ChangeLog:
PR libstdc++/117121
* include/bits/ranges_algobase.h (copy_backward): Decrement
output iterator before assigning one element through it.
* testsuite/25_algorithms/copy/108846.cc: Ensure the algorithm's
effects are correct for a single memcpyable element.
* testsuite/25_algorithms/copy_backward/108846.cc: Likewise.
* testsuite/25_algorithms/copy_n/108846.cc: Likewise.
