Duncan P. N. Exon Smith e06d77c9ae Utils: Keep distinct MDNodes distinct in MapMetadata()
Create new copies of distinct `MDNode`s instead of following the
uniquing `MDNode` logic.

Just like self-references (or other cycles), `MapMetadata()` creates a
new node.  In practice most calls use `RF_NoModuleLevelChanges`, in
which case nothing is duplicated anyway.

Part of PR22111.
