If the object is not a potential Type{...}, we can allow greater
flexibility in recursion. And for Vararg too.

Fixes #42835

Potentially useful for backport attempts: I attempted to backport this patch to 1.7-RC2 and found that it requires #42583; the latter backports cleanly, and then this patch backports cleanly. Regrettably #42583 introduces unhandled Vararg errors in our test suite, also seen on master.

I've backported this to the backport-release-1.7 branch to run a PkgEval (I am assuming this will be merged here at some point).
