Authentication-results: sourceware.org; auth=none

These functions just increment a refcount (and the base class
functions that do that are already noexcept anyway).

	* include/std/future (shared_future): Add noexcept to copy constructor
	and copy-assignment operator (LWG 2799).

Tested pwoerpc64le-linux, committed to trunk.
