Reland "[esnext] ship Object.fromEntries"

Enable --harmony-object-from-entries by default.

Object.fromEntries is a new standard library method, whose proposal
(https://tc39.github.io/proposal-object-from-entries/) is currently
at stage 3.

It simply creates a JSObject from an iterable collection of key/value
pairs, such that `Object.fromEntries([ [ "a", "b" ] ]) -> { a: "b" }`
