Linker: Avoid constructing ValueMap::MDMapT
Calling ValueMap::MD lazily constructs a ValueMap, which mallocs the
buckets. Instead of swapping constructed maps, move around the
underlying Optional<MDMapT>. This gets rid of some unnecessary malloc
traffic from r266579 (not that it showed up on a profile).
