<pre>[iOS] Run a full garbage collection on memory warning.
<https://webkit.org/b/141313>
<rdar://problem/19738024>
Reviewed by Chris Dumez.
Make sure that we run a full GC when trying to free up memory, as this might
be our last chance to execute before the kernel suspends this process.
This aligns WebKit2 with the old WebKit1 behavior.
