Subject: [patch] fix libstdc++/59548
Authentication-results: sourceware.org; auth=none

The debug-mode container base classes need copy constructors that
zero-init their members rather than copy them from the source.

_Safe_unordered_container_base also needs its move constructor to be
non-throwing to fix some FAILs for the PR 55043 tests.

Tested x86_64-linux, normal and debug modes, committed to trunk.
I also want to fix this on the branches once I've finished fixing 4.9
regressions.

	PR libstdc++/59548
	* include/debug/safe_base.h (_Safe_sequence_base): Define copy
	constructor to prevent it being implicitly defined as deleted, but
	do not copy anything.
	* include/debug/safe_unordered_base.h (_Safe_unordered_container_base):
	Define copy and move constructors similar to _Safe_sequence_base's.
	* testsuite/23_containers/unordered_map/59548.cc: New.
