For what it's worth, this test has already caught an unrelated bug, so
it's having surprising benefits. I think probably the test suite
doesn't pound on the partial symbol table as much as it could, so even
narrowly targeted partial symbol tests like this one are useful.

That sounds like an interesting idea. I do think that unit tests are
useful, and unfortunately some parts of the symbol table (especially
partial symbols) are buried a bit too deep in GDB's innards to be able
to easily do unit testing on via the test suite. Maybe maint commands
would help with that.
It would take some thinking to do well, though...
