Instead of converting them to doubles and doing double math, just do the
arithmetic operation in i64 space instead.
This gives us a ~1.25x speed-up on this kind of micro-benchmark:
(() => {
let a = -2124299999;
for (let i = 0; i < 100_000_000; ++i) {
a + a;
}
})()
Same idea for Add, Sub, and Mul.
There's a fair bit of overflowing Int32 arithmetic in some of the
JetStream benchmarks, and this seems like an obvious improvement.
