Using MCJIT is an effective workaround, e.g. https://reviews.llvm.org/D100344 .

Adding this note as a reminder to ourselves to clean up those invocations once this bug is fixed.

+Stefan and Lang for this, I assume it is likely just a missing plumbing between lli and ORC?

Hi Emilio, Mehdi,

Yep -- this was just missing plumbing. It should be fixed in 9b8e7a9d7dc7.
