tile: optimize and clean up string functions
This change cleans up the string code in a number of ways:
- For memcpy(), fix bug in prefetch and increase distance to 3 lines;
optimize for unaligned data; do all loads before wh64 to make memcpy
safe for forward-overlapping calls; etc. Performance is improved.
- Use new copy_byte() function on tilegx to spread a single byte value
out into a full word using the shufflebytes instruction.
- Clean up header include ordering to be more canonical, and remove
spurious #undefs of function names.
