I think "noreg-trivial" is a more appropriate label for this bug than "noreg-cleanup". "noreg-cleanup", as defined in the [OpenJDK Developer's Guide](https://openjdk.org/guide/) is:

"Change is a cleanup or refactoring of existing code that is covered by existing tests."

This fixes typos and removes one commented-out line, so it isn't changing any real code.
