Duncan P. N. Exon Smith 5e94641b4a ValueMapper: Add support for seeding metadata with nullptr ... Support seeding a ValueMap with nullptr for Metadata entries, a situation I didn't consider in the Metadata/Value split. I added a ValueMapper::getMappedMD accessor that returns an Optional<Metadata*> with the mapped (possibly null) metadata. IRMover needs to use this to avoid modifying the map when it's checking for unneeded subprograms. I updated a call from bugpoint since I find the new code clearer. llvm-svn: 265228		2016-04-02 17:04:38 +00:00
