Existence of semantic expr (`getSemanticExpr()`) prevents ASTWalker walking into the *original* sub expressions which may cause re-typechecking failure. For example, `ConstraintGenerator::visitArrayExpr()` assumes we already visited its elements, but that's not the case if the semantic expr exists. rdar://problem/42639255
