Jordan DeLong 38fd595342 Allocate HphpArrays in a flat mode instead of using m_inline_data
Gets HphpArrays into a flat mode using MM().objMalloc()
instead of SmartAllocator.  Various optimizations were needed to the
Make functions to get this to work out ok.  Growth still creates a
non-flat HphpArray (leaving a PromotedPayload behind so we know how
big the original allocation was).
