-----------
Potential null dereference of cached resources in
MemoryCache::pruneDeadResourcesToSize()
https://bugs.webkit.org/show_bug.cgi?id=257968
rdar://110312729
Reviewed by Sihui Liu.
While we were copying the cached resources to a vector before iterating over
them,
this vector still contained weak pointers, which would therefore become null as
we're iterating. To address the issue, we now null check these weak ptrs in the
loops, before using them.
