applies the upstream performance optimizations from
Jordi reported a 20-25% perf increase regarding file-cleaning with this changes (see comments in referenced PRs).
I was not able to replicate the demonstrated perf benefit of the upstream PRs in a PHPStan use-case.
(I remember though that I have seen blackfire profiles in the past, which had a bottleneck on PhpFileCleaner regex-matching)
Still I think its useful to keep our copied-in code as close to the upstream as possible.
