<pre>Various parts of clang generate 'previous declaration is here' notes in various
ad-hoc ways. Sometimes these notes incorrectly say 'definition'. Sometimes they
use the 'implicit' form for an implicit prior declaration, sometimes they don't
(and sometimes the implicit form handles the case where the implicit
declaration has no location, and sometimes it doesn't - PR15409). It's a mess.
We should factor out a single way of diagnosing a prior declaration and
consistently use it.</pre>
