This revision now requires changes to proceed.

I agree it would be best to generalize this.
There was a previous patch that already did that (D45173 <https://reviews.llvm.org/D45173>) and it was generic IIRC, but it got stuck and is now under wrong license.
Maybe @kparzysz is willing to relicense it thought?
