I don't think it's unreasonable to not support super old llvm
versions. This is a complex feature, and will take some time to
mature. Supporting too many LLVM versions at the outset will have some
cost. Versions before 3.8 would require supporting mcjit rather than
orc, and I don't think that'd be worth doing. I think 3.9 might be a
reasonable baseline...
