Description
Panics seem to get printed decently by the interpreted runtime, but not the JIT runtime.
To reproduce, cherry-pick 149ca1a421e461ecb1f88cb1b37fcceb9dd6b653 and then:
$ cargo build --release --target wasm32-unknown-unknown --manifest-path demo/impl/Cargo.toml && cargo run --manifest-path demo/caller/Cargo.toml
error: proc-macro derive panicked
--> demo/caller/src/main.rs:3:10

= help: message: panicked at 'oh no!', src/lib.rs:5:5
$ cargo build --release --target wasm32-unknown-unknown --manifest-path demo/impl/Cargo.toml && WATT_JIT=/git/wasmtime/target/release/libwasmtime_api.so cargo run --manifest-path demo/caller/Cargo.toml
fatal runtime error: failed to initiate panic, error 5
error: could not compile `watt-demo-caller`.
