Fix PR52822 (stable_partition move-assigns object to itself) by
scanning for the first value that doesn't match the predicate before
starting to rearrange values.

PR libstdc++/52822
* include/bits/stl_algo.h (__find_if_not): Expose in
C++98 mode.
(__find_if_not_n): Like __find_if_not, but works on and updates a
counted range instead of a bounded range.
(stable_partition): Guarantee !__pred(*__first) in call to
__stable_partition_adaptive() or __inplace_stable_partition().
(__stable_partition_adaptive): Use new precondition to avoid
moving/copying objects onto themselves. Guarantee new
precondition to recursive calls.
(__inplace_stable_partition): Use new precondition to simplify
base case, remove __last parameter. Guarantee new precondition to
recursive calls.
* testsuite/25_algorithms/stable_partition/moveable.cc (test02):
Test a sequence that starts with a value matching the predicate.
* testsuite/25_algorithms/stable_partition/pr52822.cc:
Test vectors, which have a destructive self-move-assignment.
