Rollup merge of #125030 - saethlin:ui-test-false-positives, r=compiler-errors

Fix some minor issues from the ui-test auto-porting

I'm not sure if these count as false positives, because well, starting a comment with `// incremental` was probably a valid compiletest directive.

But anyway, these tests directives became clearly goofy and now with the better syntax we can straighten things out.
