1849204 - Provide a generic AtomHashKey and RefPtrAtomHashKey

Status: RESOLVED FIXED

(Core :: XPCOM, enhancement)

Description

[Markus Stange [:mstange]]

I'm filing this bug as per Emilio's request in this review comment:

  using MapType = nsTHashMap<nsPtrHashKey<nsAtom>, MiscContainer*>;

Atoms have a pre-computed hash which is probably better distributed than nsPtrHashKey. But I see we don't have a ready-to-use hash key implementation for them. I guess AtomKey from nsGridContainerFrame.h would do, but that uses mozilla::HashMap.

Let's add a generic AtomHashKey and RefPtrAtomHashKey.
