Merge r187270 - bmalloc: Shrink the super chunk size (again)
https://bugs.webkit.org/show_bug.cgi?id=147240
Reviewed by Andreas Kling.
Shrinking to 8MB reduced VM exhaustion crashes but did not eliminate them.
Let's try 4MB.
(My previous comment was that the maximum fast object was 2MB. But it
was 4MB! Now it's 2MB for realsies.)
