  Log Message:
  -----------
  [AST][RecoveryExpr] Add error-bit to NestNameSpecifierDependence and TemplateNameDependence.

Summary:
We might lose the error-bit if the error-bit goes through the code path
"error type/expr" -> "error template argument" -> "nested name specifier" ->
... -> "template Specialization type"

Template name also needs this, as a template can be nested into
an error specifier, e.g. templateName apply in
`TC<decltype(<recovery-expr>(Foo, int()))>::template apply`
