[PATCH] D20743: [GVN] Preserve !range metadata when PRE'ing loads

[Daniel Berlin via llvm-commits]

dberlin added a comment.

(as an aside, having to copy every type of metadata separately everywhere
seems ... bad, i'm kind of surprised we can't just say "transfer metadata
of these from this instruction to this one" at a minimum as a utility
function)))
