PoC patch based on https://crbug.com/462733

I'm uploading (not for final review, still comments about it very much welcomed), a PoC patch based on https://crbug.com/462733

With this (and plus the fix of commenting the reader deletion ttps://bugs.webkit.org/show_bug.cgi?id=159089 ) I get this results:

kangaroos:   690 MB WebProcess memory usage --  <1sec to load from disk -- 15 sec first loop --- 15 sec second lop
bigbuck5s:   300 MB WebProcess memory usage --  <1sec to load from disk -- 5 sec first loop --- 5 sec second lop
bigbuck20s: 1030 MB WebProcess memory usage --  <1sec to load from disk -- 20 sec first loop --- 20 sec second lop


So looks like almost fixed.

But there is like some bugs on the current patch, as the GIF sometimes (1 every 5 tries) doesn't play on the first load and has to be re-tried until it plays
