This partially reverts commit 561078480f.
If we avoid all debug mode checks when erasing elements then we fail to
invalidate safe iterators to the removed elements. This reverts the
recent changes in r12-4083 and r12-4233, restoring the debug checking.
libstdc++-v3/ChangeLog:
* include/experimental/deque (erase, erase_if): Revert changes
to avoid debug mode overhead.
* include/experimental/map (erase, erase_if): Likewise.
* include/experimental/set (erase, erase_if): Likewise.
* include/experimental/unordered_map (erase, erase_if):
Likewise.
* include/experimental/unordered_set (erase, erase_if):
Likewise.
* include/experimental/vector (erase, erase_if): Likewise.
* include/std/deque (erase, erase_if): Likewise.
* include/std/map (erase, erase_if): Likewise.
* include/std/set (erase, erase_if): Likewise.
* include/std/unordered_map (erase, erase_if): Likewise.
* include/std/unordered_set (erase, erase_if): Likewise.
* include/std/vector (erase, erase_if): Likewise.
