largefiles: only cache largefiles in new heads This fixes a serious performance regression in largefiles introduced in Mercurial 2.1. Caching new largefiles on pull is necessary, because otherwise largefiles will be missing (and unable to be downloaded) when the user tries to merge or rebase a new head with an old one. But this is an expensive operation and should only be done for heads that are new from the pull, rather than on all heads in the repository.
