// f64 micro benchmark (Cranelift JIT)
// Requirements:
//   - Build with: cargo build --release --features cranelift-jit
//   - Run with:   NYASH_JIT_EXEC=1 NYASH_JIT_THRESHOLD=1 NYASH_JIT_NATIVE_F64=1 \
//                 ./target/release/nyash --backend vm examples/ny_bench_f64.hako
// Notes:
//   - VM backend alone may not support f64 BinOp/Compare; use JIT as above.
