OS X: try cheap ascii .lower() in normcase before making full unicode dance

This is similar to what is done in encoding.lower, introduced in c481761033bd.

This has been seen making 'hg up' and 'hg st' in a 50000+ files repo 13%
faster.

This might make Mercurial slightly slower for users who mainly use non-ASCII
filenames. That is a reasonable trade-off.

  $ "$TESTDIR/hghave" inotify || exit 80
  $ hg init
  $ echo "[extensions]" >> $HGRCPATH
  $ echo "inotify=" >> $HGRCPATH

inserve

  $ hg inserve -d --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"

let the daemon finish its stuff

  $ sleep 1

empty

  $ hg debuginotify
  directories being watched:
    /
    .hg/
  $ mkdir a
  $ sleep 1

only 'a

  $ hg debuginotify
  directories being watched:
    /
    .hg/
    a/
  $ rmdir a
  $ sleep 1

empty again

  $ hg debuginotify
  directories being watched:
    /
    .hg/
  $ kill `cat hg.pid`
