[PATCH] D53475: Create ConstantExpr class

Looks fine as far as it goes, but we're going to need to change all the places that skip past ExprWithCleanups to also step over this node. Since both nodes represent the boundary of a particular kind of full-expression, it'd make sense to me for them to at least have a common base class for such "skipping" purposes.

+  VisitExpr(S);
+  VisitExpr(S->getSubExpr());
+}
----------------
This is unnecessary: this visitor visits the children of the node for you.
