This is a follow-up of https://bugs.webkit.org/show_bug.cgi?id=89236. 

The initial idea is use small heap size when system is under memory pressure. I ended up with putting platform-specific GC policy in GCActivityCallback. However I found it isn't safe to do GC in didAllocate. The only place it makes sense and is safe to collect garbage is reportExtraMemoryCost.
