This adds a global protector to guard the lookup of "resolve" on the %Promise% intrinsic object (the initial Promise constructor), making sure that Promise.resolve yields the initial builtin method. We use this protector to avoid the lookup of "resolve" all the time inside of Promise.all and Promise.race, when called with constructor being the %Promise% intrinsic object. This improves the performance on the parallel-async-es2017-native benchmark by roughly 2-3%.
