[clang][NFC]Remove unused variable (#211983)

The patch resolves the following warning.
```bash
clang/lib/StaticAnalyzer/Checkers/RetainCountChecker/RetainCountDiagnostics.cpp:504:16: warning: variable ‘i’ set but not used [-Wunused-but-set-variable=]
  504 |       unsigned i = 0;
      |                ^
```

A count variable was set and incremented inside of a for loop but never
actually used inside of the loop or anywhere else in its scope.

[Passes] Replace PassInfoMixin with {Optional,Required}PassInfoMixin

There were a couple passes that landed after the mass migration that
need to be updated to eventually make PassInfoMixin private. For backend
passes I looked at whether LegacyPM passes called skipFunction rather
than whether or not they should be enabled to try and preserve existing
behavior where possible.

We still need to wait a bit in order to avoid PassInfoMixin to a detail
namespace and fully remove isRequired from PassInfoMixin given there are
a lot of out-of-tree passes that have not yet been moved over. I'm
hoping to have patches out within a week.
