> Do we have a use case for adding this as an AST matcher? For instance, one of the first things I'd want to do with such a matcher is traverse down to the association list, but I don't think that's possible currently. Should we add all of the AST functionality or just wait until there's a concrete use case and add the AST matchers bits at that point?
I mostly did this because that's what I did in the previous case from Feb 2019: reviews.llvm.org/D58292, for ChooseExpr, and I was cribbing off my old code.

However, on further reflection, I remembered that this patch actually removes a case that was locally defining this matcher already: see the removed lines in clang/lib/Analysis/ExprMutationAnalyzer.cpp in this patch. So, I think that is enough of a case for adding this.
