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

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
