Allocates space for the main heap, and stores a reference to this heap at 8012BAA0

* V0 is assigned to the pointer to the heap node containing the allocated space
Allocates a block of space on the main heap.

* V0 is assigned to the address the heap is stored at.

Creates a heap space with an initial node, and attaches it to some structure. If the start address is not aligned to a 0x10 boundary, the space will be aligned to the next aligned address. Seems to only be called when allocating the main heap, and the "actor space" heap within the main heap.

 Quite massive. Performs various checks and calls to create the playable game world (non file select). Called once every time a new area is loaded (twice for Silver Gauntlet's chest though?)
