dirstate: remove excess attribute lookups for dirstate.status (issue5714)
A recent refactor added a layer of abstraction to the dirstate which makes doing
things like 'foo in dirstate' now require some extra Python attribute lookups.
This is causing a 100ms slow down in hg status for mozilla-central.
The fix is to hoist the inner dict's functions onto the main class once the lazy
loading it complete, as well as store the actual functions before doing the
status loop (as is done for other such functions).
In my testing, it seems to address the performance regression, but we'll
need to see the perf run results to know for sure.
