dir.c: git-status: avoid is_excluded checks for tracked files
Checking if a file is in the index is much faster (hashtable lookup) than
checking if the file is excluded (linear search over exclude patterns).
Skip is_excluded checks for files: move the cache_name_exists check from
treat_file to treat_one_path and return early if the file is tracked.
This can safely be done as all other code paths also return path_ignored
for tracked files, and dir_add_ignored skips tracked files as well.
There's just one line left in treat_file, so move this to treat_one_path
as well.
Here's some performance data for git-status from the linux and WebKit
repos (best of 10 runs on a Debian Linux on SSD, core.preloadIndex=true):
| status | status --ignored
| linux | WebKit | linux | WebKit
-------+-------+--------+-------+---------
before | 0.218 | 1.583 | 0.321 | 2.579
after | 0.156 | 0.988 | 0.202 | 1.279
gain | 1.397 | 1.602 | 1.589 | 2.016
