localrepo: micro-optimize __len__() to bypass repoview

Since len(changelog) isn't overridden, we don't have to validate a cache of
unfiltered changelog.

  $ python -m timeit -n 10000 \
           -s 'from mercurial import hg, ui; repo = hg.repository(ui.ui());' \
           'len(repo)'
  orig) 10000 loops, best of 3: 32.1 usec per loop
  new)  10000 loops, best of 3: 1.79 usec per loop

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
