The helpers of the typed-array callback methods (forEach, map, filter, some, every, find, findIndex, findLast, findLastIndex, reduce, reduceRight) called their callback through the closure's code pointer on every element, and one helper served every call with the same signature, so the callback was never inlined. A literal callback now gets a helper of its own, as for the array methods, and the constant-callback census accepts the typed-array helpers, so the helper calls that function directly. The visit is now a loop on its own counter, `for (let i = 0; i < a.length; i++)` or down from the last index, instead of a loop on a counter declared before it, so the counter is an integer and element reads need no index test. reduce and reduceRight without an initial value read their seed at the first visited index and start one past it. Adds reduce, some and map callbacks to the typed-array-kernels workload.
