Hit a bit of a snag with this upgrade.

thread 'main' panicked at /private/tmp/nix-build-roc_cli-0.0.1.drv-0/cargo-vendor-dir/inkwell-0.2.0/src/types/enums.rs:475:13:
Found StructType(StructType { struct_type: Type { address: 0x1338c91b8, llvm_type: "{ [0 x i64], [3 x i64], i8, [7 x i8] }" } }) but expected the PointerType variant
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Investigated a bit, it might be best to wait and maybe land LLVM upgrade first, this looks to be unrelated to the Path upgrade.

Closing as this has gone a bit stale and it will be easier to start from scratch.
