Benedikt Meurer e122fc4565 [builtins] Add fast-path for the Promise.resolve lookup.
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%.
