The 'declare' construct is the first of two 'declaration' level constructs, so it is legal in any place a declaration is, including as a statement, which this accomplishes by wrapping it in a DeclStmt. All clauses on this have a 'same scope' requirement, which this enforces as declaration context instead, which makes it possible to implement these as a template. The 'link' and 'device_resident' clauses are also added, which have some similar/small restrictions, but are otherwise pretty rote. This patch implements all of the above.
