Improve wording of "cannot multiply" type error

For example, if you had this code:

    fn foo(x: i32, y: f32) -> f32 {
        x * y
    }

You would get this error:

    error[E0277]: cannot multiply `f32` to `i32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`

However, that's not usually how people describe multiplication. People
usually describe multiplication like how the division error words it:

    error[E0277]: cannot divide `i32` by `f32`
     --> src/lib.rs:2:7
      |
    2 |     x / y
      |       ^ no implementation for `i32 / f32`
      |
      = help: the trait `Div<f32>` is not implemented for `i32`

So that's what this change does. It changes this:

    error[E0277]: cannot multiply `f32` to `i32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`

To this:

    error[E0277]: cannot multiply `i32` by `f32`
     --> src/lib.rs:2:7
      |
    2 |     x * y
      |       ^ no implementation for `i32 * f32`
      |
      = help: the trait `Mul<f32>` is not implemented for `i32`
