What we require is being able to work at the MC rather and IR level, because we want exact control over which instructions are emitted I'm not familiar with `ORCJit`, but from a quick look at the doc <https://llvm.org/docs/ORCv2.html#lljit-and-lllazyjit> it looks like it should be doable: `replacements for earlier LLVM JIT APIs (e.g. MCJIT)`.

Yep -- you can definitely load up object files directly.

We don't have plans to remove it any time soon, but it's no longer being actively developed.
