Proposed changes

There were a number of subtleties, and unfortunately the GDB documentation is essentially non-existent, but this resolves the issue. It does make the output not as pretty since I need to print the storage index instead of the component suffix. I don't know of an easy way around this, though.

@wthrowe would you mind testing this on your machine in case there's some GDB version-dependent behavior going on?

I'm leaving the evaluation string so we can revisit this in the future without having to learn all that again.

Upgrade instructions

Code review checklist

• The code is documented and the documentation renders correctly. Run
  make doc to generate the documentation locally into BUILD_DIR/docs/html.
  Then open index.html.
• The code follows the stylistic and code quality guidelines listed in the
  code review guide.
• The PR lists upgrade instructions and is labeled bugfix or
  new feature if appropriate.
