Addresses UK 172

This issue is a response to NB comment UK-172

The functions `quick_exit` and `at_quick_exit` should be added to the required features of `<cstdlib>` in a freestanding implementation.

This comment was rejected in Summit saying neither `at_exit` nor `at_quick_exit` should be required. This suggests the comment was misread, as `atexit` is already required to be supported. If the LWG really did wish to not require the registration functions be supported, then a separate issue should be opened to change the current standard.

Given both `exit` and `atexit` are required, the UK panel feels it is appropriate to require the new `quick_exit` facility is similarly supported.

Proposed resolution:

Ammend p3 Freestanding implementations 16.4.2.4 [compliance]

> 3 The supplied version of the header `<cstdlib>` shall declare at least the functions `abort()`, `atexit()`, `at_quick_exit`, and `exit()`, and `quick_exit`(17.5 [support.start.term]). The other headers listed in this table shall meet the same requirements as for a hosted implementation.
