The fix is easy. I wrote the code but never got around to pushing it.

It just needs to be a template in druntime. Hypothetically you could make it
inline a loop but this might hurt LDC and GDC.

arrayOp actually supports memset but making the array lowering use arrayOp
would make it end up using itself.

I also looked into using an arbitrary set memset in the backend but yuck.
