I just removed this comment, since I couldn't think of a useful comment
to put before a destructor.

I've changed it. I think this was something I meant to do and then
forgot to complete.
Pedro> But FLAGS isn't a hash table, right? The original comment said:
Pedro> /* Look up the type T in the typedef hash table in with FLAGS.
Pedro> ^^^^^^^
Pedro> I wonder whether that was a typo for "within".
Pedro> Maybe this could say something about local/global too.
I've rewritten this comment, let me know what you think.

commit cc694e06afaf2072e6e02465ca6f6d33849fb9b3
Author: Tom Tromey <tom@tromey.com>
Date: Wed Mar 14 16:38:02 2018 -0600
C++-ify typedef hash
This changes the typedef_hash_table structure to be a C++ class. It
adds constructors and destructors and changes some functions to be
methods of the class. Then it changes the various users of this class
to adapt. This allows for the removal of some cleanups.
Regression tested by the buildbot.
