US 14-029 6.5.1p2 [basic.lookup.general] Define "program point" CWG3058

[wg21bot]

There is no clear definition of a program point, which is fundamental to a lot of the syntax rules in many clauses. This reference in name lookup seems the closest to a definition, but we might prefer an entry in clause 3?

Proposed change:

Define a program point such that, in translation phase 7, "There is a program point between every pair of adjacent tokens, before the first token of the translation unit, and after the last token of the translation unit."
