1589108 - Assert that the current realm's global is not gray on entry to the JS API

Status: RESOLVED FIXED

(Core :: JavaScript: GC, task, P1)

Description

[Jon Coppeard (:jonco) (PTO until 5th Jan)]

This came up in bug 1399866 where we use AutoRealmUnchecked to enter a gray realm when remapping wrappers and then call the embedding remap hook. This can enter the JS API still in the gray realm.

We can prevent this by adding a check to the context checks we do at most API entry points.
