All new target-independent intrinsics need to be documented in LangRef.

Thinking about it a bit, this seems like a reasonable intrinsic to support across all (or at least most) targets; the meaning is well-defined, and it can't be computed from any of the other frame-related intrinsics, so I think it makes sense to support cross-platform.

That said, maybe instead of adding a new intrinsic, we should rename llvm.addressofreturnaddress?  It's the same thing on x86, and addressofreturnaddress doesn't really make sense on other targets anyway.
