Darius Mercadier b0abfb4fc7 [heap] Add fast allocation strategy (--gc-freelist-strategy=1) 
This CL adds a new FreeList strategy, that can be turned on by using flag
`--gc-freelist-strategy=1`.  It is inspired by FreeListLegacy, and differs from
it in the following ways:
 - Only has 3 categories: Medium, Large and Huge.
 - Any block that would have belong to tiniest, tiny or small in FreeListLegacy
   is considered wasted.
 - Allocation is done only in Huge, Medium and Large (in that order), using a
   first-fit strategy (only the first block of each freelist is ever considered
   though).
 - Performances is supposed to be better than FreeListLegacy, but memory usage
   should be higher (because fragmentation will probably be higher).
