https://reviews.llvm.org/D41118 adds real (non-empty) ranges for diagnostics.
I've copied all the changes you've made here with some slight tweaks, as they were required for that too.

If you like it as-is, probably easiest to land that instead.
But I'm also happy for you to land this and I'll merge. Up to you.
