These two tests were failing before this change (the files were considered ignored).

These three tests were already passing before the change. I added them just to verify that the cases the transformations were targeting still work as intended when the transformations are removed.

Fixes the problem in eslint/eslint#17964 (comment)
In the code that calculates global ignores, there were still some transformations of patterns that, I believe, were needed in some previous versions, but are now causing unintended behavior.
For example, ignore pattern
foo/*/should not match filefoo/a.js.I removed all those transformations and added several tests that demonstrate the difference in behavior after this change, and also a few regression tests.
