[PATCH] D34285: [SROA] Be smarter when copying metadata to retyped loads

[Chandler Carruth via Phabricator via llvm-commits]

chandlerc added a comment.

FYI, I started looking at this. I think a somewhat substantially different refactoring of the instcombine API makes this much simpler by *only* extracting the logic for nonnull and range propagation rather than extracting all of it.

I've almost got the refactoring done, and I'm happy to land the rest for you rather than making you go through a bunch of iterations of code review.
