SE-0138: Minor update. Array.withUnsafeBytes is nonmutating.

Browse Source 
The "mutating" keyword should not have been on this API. The example
code in SE-0138 uses it as a nonmutating API.

(The mutating keyword was a temporary workaround that should never
have been carried over to the swift-3.0-branch).

<rdar://28614519> [swift-3.0-branch] Remove "mutating" keyword from Array.withUnsafeBytes
