largefiles: show status for files added on another branch correctly

original implementation can't show status for largefiles added on
another branch correctly, because:

    1. no STANDIN file/directory corresponded to specified patterns
       exists 'local' side branch (this also causes unexpected
       'performance boost' root choice), and

    2. 'filefn()' for matcher creation only examines 2nd context, so
       files()' of created matcher is not updated expectedly (this
       causes unexpected behavior of 'dirstate.status()')

this patch fixes this problem by examining both 1st/2nd context for
files/directories not known to each other.

in this patch, 1st context is examined only not in 'parentworking'
case for performance efficiency, because 2nd context (= working
context) should have enough information about removed files in
'parentworking' case.
