Expose IRGen API to add the default IR attributes to a function definition.

I've also made a stab at imposing some more order on where and how we add
attributes; this part should be NFC.  I wasn't sure whether the CUDA use
case for libdevice should propagate CPU/features attributes, so there's a
bit of unnecessary duplication.
