Summary FontFallbackList: Glyph pages waste a lot of memory.

The m_pages hash map in FontFallbackList is defined as follows: typedef HashMap<int, GlyphPageTreeNode*> GlyphPages; GlyphPages m_pages; This uses the default HashMap minimum table size of 64 buckets which is quite wasteful in many cases. One idea is to lower the minimum table size using hash traits. A patch will follow that lowers it to 16, which reduces memory consumption by ~900 kB when loading the full HTML5 spec.
