Nice!



================
Comment at: clang/lib/Sema/SemaExprCXX.cpp:8310
+    // to RecoveryExpr.
+    // FIXME: we lose source locations for RecoveryExpr, as TypoExpr doesn't
+    // track source locations.
----------------
This seems reasonably straightforward to fix - there shouldn't be a lot of TypoExprs so we can just add a member. Worth doing I think.


================
Comment at: clang/lib/Sema/SemaExprCXX.cpp:8314
+      using Base = TreeTransform<TyposReplace>;
+      TyposReplace(Sema &SemaRef) : Base(SemaRef) {}
+      ExprResult TransformTypoExpr(TypoExpr *E) {
----------------
Can't you just write this as `: TreeTransform(SemaRef) {}`, and drop the using?
