The RType field isn't needed when performing type assertions from
non-empty interface types, because we use the ITab field instead. But
the inline body exporter didn't know to expect this.
It's possible we could use a single bool to distinguish whether
we're serializing the RType or ITab field, but using two is simpler
and seems safer.
Fixes #54302.
