i64.mul

Pops two

`i64`

values off the stack, multiples them together, and then
pushes the result back on to the stack.
$result = $first * $second

```
i64.mul
```

i64 | The first value to be multipled. |

i64 | The second value to be multipled. |

i64 | The result of multipling the first and second values together. |

;; Push the i64 value 4 onto the stack i64.const 4 ;; Push the i64 value 3 onto the stack i64.const 3 ;; Pop the two i64 values off the stack, multiply them together and ;; push the result back onto the stack i64.mul ;; The stack contains an i64 value of 12
