There are objfiles without a BFD.  E.g., Java makes one.  Maybe the JIT
stuff too.  These do still have a name -- objfiles are required to have
a name.

I don't understand this.  It doesn't seem any different from the present
situation.

I think it is fine if you want to have different names for printing and
for canonical use.  It's also ok to change the BFD cache to work
differently (it realpaths since that is convenient and gets good caching
behavior; but you could store some other form of the path instead and
accept cache misses).

It's worth noting that sometimes it is useful to see the full path.
E.g., it can be a way to notice that gdb or the inferior is doing
something unexpected.
