* Implement faster address translation and write tracking on the MMU * Rename MemoryAlloc to MemoryManagement, and other nits * Support multi-level page tables * Fix typo * Reword comment a bit * Support scalar vector loads/stores on the memory fast path, and minor fixes * Add missing cast * Alignment * Fix VirtualFree function signature * Change MemoryProtection enum to uint aswell for consistency
