I have started, but I could use some help :-)

The items I have in mind:
1) make the arm inline version work on thumb
2) add a Subtarget->getMinRepStrSizeThreshold to ARM (maybe with a
more generic name)
3) make the high level memcpy lowering identical on ARM and X86
4) move it to a common place.
5) move the code that lowers to a call to a common place.
6) implement a generic inline version that works on every arch (just a
bunch of load/store).

I should have 2 implemented on Friday. If someone could implement 1 it
would be great :-)

Cheers,
