MIPS: Adapt Danno's Track Allocation Info idea to fast literals.

Port r13330 (6d9ce8a8)

Original commit message:
Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, we store an AllocationSiteInfo object right after the JSArray, with a pointer to the boilerplate object. Later, if the array transitions we check for the continued existence of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to transition the boilerplate array as well.
