Fix All The Things Release

Breaking Changes

• Remove Symbol.species from Promise.all and Promise.race (#34) per ES6 errata

Fixes (shim)

• Firefox has enumerable Promise static methods
• prevent crashes in older Firefox when checking if Array methods ToLength correctly
• Reflect.enumerate: ensure correct property ordering in Firefox 19 (and likely others)
• Ensure that toLengthsCorrectly returns true when it passes, instead of undefined
• Don't call Reflect.construct unless it's actually present
• Ensure Map and Set do not have an own constructor property (#368)
• Add missing checks to Promise.resolve and Promise.reject (#379)
• Map: older v8s have a SameValueZero bug when a Map has a size > 4 (#378)
• Map: when provided with an iterable that yields non-Object values, should throw
• Promise: Make sure to shim broken implementations in Chrome 49 Canary
• Promise: Chrome does not retrieve a thenable's .then synchronously (#372)

New Stuff

• Add RegExp.prototype[Symbol.{match,search,split,replace}]
• support Symbol.match in RegExp constructor
• add Symbol.match and ensure String#{match, startsWith, endsWith, includes} support it
• add Symbol.split and ensure String#split supports it
• add Symbol.replace and ensure String#replace supports it
• add Symbol.search and ensure String#search supports it

Robustness

• Add and use ES.ToString so as not to rely on the global String

Dev Deps

• update eslint, jscs, mocha, uglify-js, es5-shim, grunt-saucelabs

Tests

• bail out of some tests when the feature isn't present, to clean up native test failure output
• test up to node v5.1
• fix npm run test:native
• Ensure Promise.{reject,resolve} throws when the receiver is a primitive (#379)
• Further ensure that Promise.resolve/reject work with a non-promise receiver (#379)
