Looks good to me. Sorry for missing this in my PR about exists permissions. Do you know if that was because I overlooked a test, or was it because we didn't have any IRT tests which would've caught this?
Looks like this depends on #1440, so it should not be merged until the former is.

PR #1422 simplified the translation of permissions of the form
exists x:tp. eq(e)so that, instead of generating a dependent pair typeSigma tp (\x -> unit)with a trivial second projection, these are now just translated directly to (the translation of) the typetpof the existential variable. Unfortunately, that PR forgot to update the IRT translations, so that any recursive permission defined using IRTs that has, say, a bitvector value in it is translated incorrectly and generates a Coq error.
