[PATCH 0/2] Add pretty-printer base class and new methods

[Tom Tromey]

This adds a pretty-printer base class, to make it possible for gdb to
extend the pretty-printer API over time.

Then, a couple of new methods are added and the no-op array printer is
changed to use these, rather than the current approach of adding an
attribute and hoping it works ok.

Regression tested on x86-64 Fedora 36.
