Use switch here because the aligning instruction requires immediate value for shift count. Requirements:

Copy less than 16 bytes
Fast way when copy size doesn't exceed 512 bytes
Make store aligned when copy size exceeds 512 bytes, and make sure the first 15 bytes are copied, because unaligned copy functions require up to 15 bytes backwards access.
For aligned copy
Copy 256-byte blocks
Copy whatever left
For copy with unaligned load
Copy whatever left
