match: remove unnecessary optimization where visitdir() returns 'all'
Match's visitdir() was prematurely optimized to return 'all' in some cases, so
that the caller would not have to call it for directories within the current
directory. This change makes the visitdir system less flexible for future
changes, such as making visitdir consider the match's include and exclude
patterns.
As a demonstration of this optimization not actually improving performance,
I ran 'hg files -r . media' on the Mozilla repository, stored as treemanifest
revlogs.
With best of ten tries, the command took 1.07s both with and without the
optimization, even though the optimization reduced the calls from visitdir()
from 987 to 51.
