Addresses DE-21

23.2.1/11 provides a general no-throw guarantee forerase() container functions, exceptions from this areexplicitly mentioned for individual containers. Because ofits different name, forward_list's erase_after() function isnot ruled by this but should so.

[Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102.]

Proposed resolution:

Add a "Throws: Nothing" clause to botherase_after overloads in 23.3.3.4, [forwardlist.modifiers].
