To mitigate the dangers of silently breaking ADL when moving enums into unnamed
namespaces (see the commit message of 206b5b2661
"New loplugin:external"), note all functions that are affected. (The plan is to
extend loplugin:external further to also warn about classes and class templates,
and the code to identify affected functions already takes that into account, so
some parts of that code are not actually relevant for enums.)
But it appears that none of the functions that are actually affected by the
changes in this commit relied on being found through ADL, so no adaptions were
necessary for them.
(clang::DeclContext::collectAllContexts is non-const, which recursively means
that External's Visit... functions must take non-const Decl*. Which required
compilerplugins/clang/sharedvisitor/analyzer.cxx to be generalized to support
such Visit... functions with non-const Decl* parameters.)
