Very useful for debugging largefiles "performance" issues.
This is used for testing

util: fold ENOENT check into unlinkpath, controlled by new ignoremissing flag
Refactor a common pattern.
largefiles: don't walk through all ignored files
Problem: 'hg status' with largefiles enabled would walk through all the files
that .hgignore said should be ignored. That made it slow if a lot of files were
.hgignored or the cache was cold.
It seems like there was a reason to this, but other improvements has rendered
this unnecessary.
Solution: .hgignore is now only ignored when that is requested (--ignore).
This is a minimal 'stable' change. There is room for other improvement.
