[llvm-dev] Retrieving DbgInfoIntrinsics for a given value

If I have an llvm value "<16 x float> addrspace(1)* %in", and in the LLVM
IR, there is a @llvm.dbg.value like:

call void @llvm.dbg.value(metadata <16 x float> addrspace(1)* %in, i64 0,
metadata !216, metadata !28), !dbg !217

How I can retrieve this @llvm.dbg.value when I have "%in"?

Since Metadata is not a part of the uselist anymore, is there some way
rather than iterate over every instructions in the function to get this
