   ASTContext &Context = AstUnit->getASTContext();
-  auto Matches = ast_matchers::match(wrapMatcher(Matcher), Context);
+  auto Matches = ast_matchers::match(
+      traverse(ast_type_traits::TK_AsIs, wrapMatcher(Matcher)), Context);

> You say "the test" as though there's only one. There are numerous tests which use `matchStmt`. Do *all* of the tests require `AsIs`? (I think that's an example of what's causing some of the confusion @shafik and I had and I'm trying to ensure his question gets answered and that I'm fully understanding your changes.) From spot-checking, it looks like there are tests using `matchStmt` that don't need `AsIs` traversal and that this sort of cleanup work could happen in the future, but for now you're going with the easiest approach instead of expanding the test coverage for ignoring implicit nodes; is that correct?
I said "the" test because there is one `StencilTest` class inside one `StencilTest.cpp`. Perhaps not a word you would use, but that's not something to get stuck on hopefully.

Yes, it is possible that someone could make `matchStmt` take an explicit `TraversalKind`, but I didn't see the need to do that in this patch. This patch maintains the status quo as much as possible while also making it possible to change the default.
