@lebedev.ri Thanks for looking at this patch. The following two other patches are correlated so I just added them here.

Could you be more specific where to add langref for this intrinsic?

Currently, I am guarding the usage of intrinsics in clang under bpf, so other targets won't be able to use this.
If there is a demand we can implement a callback function in TargetInfo so different targets can decide whether
they want to use this intrinsics.

We can implement the default expansion, do you know where is the proper place to do that?
