REGRESSION(276827@main): Possible null pointer dereferencing when an image
frame finishes decoding while the document is getting closed
https://bugs.webkit.org/show_bug.cgi?id=279221
rdar://133487516
Reviewed by Simon Fraser.
When the image decoding thread finishes decoding an image frame, don't cache
this frame unless the ImageDecoder is still available.
The callers of cacheMetadataAtIndex() and cacheNativeImageAtIndex() will ensure
the ImageDecoder is still available before calling these functions.
