largefiles: performance improvement for bypass route choice

original implementation chooses 'performance boost' route, if there
are any entries with which specified pattern matches in lfdirstate,
because there was no easy way to examine whether it is related to
context or not for 'directory pattern'.

but this requires full scan of lfdirstate entries in the worst case.

so, this patch uses 'dirs()' newly added to dirstate to avoid full
scan of lfdirstate.
