Fallout where types must be specified.

This is due to a [breaking-change] to operators. The primary affected
code is uses of the `Rng` trait where we used to (incorrectly) infer the
right-hand-side type from the left-hand-side, in the case that the LHS
type was a scalar like `i32`. The fix is to add a type annotation like
`x + rng.gen::<i32>()`.
