Code in benchmark directory sometimes uses `function () {}` for
anonymous callbacks and sometimes uses `() => {}`. Multi-line arrays
sometimes have a trailing comma and sometimes do not. Update to always
use arrow functions for anonymous callbacks and trailing commas for
multiline arrays.

// When calling .end(buffer) right away, this triggers a "hot path"
|
|
// optimization in http.js, to avoid an extra write call.
|
|
//
|
|
// However, the overhead of copying a large buffer is higher than
|
|
// the overhead of an extra write() call, so the hot path was not
|
|
// always as hot as it could be.

|
// Verify that our assumptions are valid.
