[llvm] [IR] Correct Value::use_iterator::value_type. (PR #120609)

[Craig Topper via llvm-commits]

https://github.com/topperc created https://github.com/llvm/llvm-project/pull/120609

operator* for this iterator returns Use& so I think the value_type should be Use not Use*.

Noticed while comparing with SDNode::use_iterator.
