Yes, I am still interested in working on this. For now, I've split out some changes that don't require any modifications in `SourceLocation` into https://reviews.llvm.org/D89705.

> A general comment is that there are a couple of functional changes in this patch, where hash values are changing and data structures are being changed, but they're buried in the noise of the refactoring that's going on at the same time. I suggest splitting this up at least into two

Will do.
