Addresses US-198

promise::set_exception can be called with a null pointer, but none of the descriptions of the get() functions for the three types of futures say what happens for this case.

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

Proposed resolution:

Add the following sentence to the end of 30.6.5/22: The behavior of a program that calls set_exception with a null pointer is undefined.
