Looks good so far. Will try to push this tomorrow.
I got distracted trying to figure out why LLVM 22 is segfaulting in
llvm::orc::ExecutionSession::IL_emit(). It's not out ... yet. I was
worried that might be a clue about problems with the backported
SectionMemoryManager nonsense, but (un)fortunately it also still
crashes with the JITLink patch[1]. Will need to chase this down...
