[v2,11/14] update-index: remove ce_match_stat(), all macros

Commit Message

From: Derrick Stolee <[e-mail]>

The final index compatibility macro to remove from the update-index
builtin is ce_match_stat(). Further, this is the last use of that macro
anywhere, so it should be removed.

There are some remaining references in the racy-git.txt technical
document that are updated to ie_match_stat().
