To remove a specifc kind of metadata from an instruction, use setMetadata(kind, NULL). To remove all the metadata, call getAllMetadata first, then iterate over the kinds in the returned collection and remove them via the first method.

Keep in mind that this will not remove the actual MDNode and will not remove any dbg.declare or dbg.value calls if that's what interests you.
