Subject: [PATCH] PR libstdc++/70966 fix lifetime bug for default resource

Similar to what I did for the new_delete_resource and
null_memory_resource objects, this makes the atomic<memory_resource*>
immortal. This ensure it can still be used after static destructors
start running.

	PR libstdc++/70966
	* include/experimental/memory_resource (__get_default_resource): Use
	placement new to create an object with dynamic storage duration.

Tested powerpc64le-linux, committed to trunk.
