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

SectionMemoryManager nonsense, but (un)fortunately it also still
crashes with the JITLink patch[1].  Will need to chase this down...
