I had a little fun today kicking the crap out of C's memcpy

Request for help: I don't have a Linux system running on real
hardware at this time, nor do I have a wide range of platforms
and machines to test with. If you'd like to help me with this
potentially foolish endeavor, please run the program on your
hardware and send me the results.
Feedback, advise, and pull requests to improve the
implementation are most welcome.
Just a little remark. Alignment has also an extremely heavy
impact on the performance of memcpy(). Does your test include
it?
I asked on IRC yesterday and actually tHose memcpy are not the
memcpy we use to copy wide chunks, apparently it's rather for an
internal druntime thing, i.e cpy type to type so likely always
aligned.
