addremove: only query dirstate once per path
Previously the addremove code queried the dirstate 4 times per path. Now it
only does so once. On a large repo this brings addremove from 9.5 seconds
to 8.35 seconds (12%).

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
