CacheInitialJSArrayMaps was called in the middle of
JSFunction::SetPrototype even though this only happens during
bootstrapping given that Array.prototype os non-configurable and
non-writable.

Changes:
- Rename CacheInitialArrayMaps to InitializeJSArrayMaps
- Add more explicit checks in InitializeJSArrayMaps to link back
  to the Context indices for better code searching
