This is used for a different feature: to be able to inject code into a
program being debugged.  See gdb/compile/ in the GDB repository (and
the corresponding docs in the manual, gdb/doc/gdb.texinfo).

And I don't think this is implemented as a GCC plugin.  AFAIU, GDB
dynamically loads libcc1.so to invoke the compiler functions.

That's correct, GDB completes on symbols using its own code.
File-name completion uses Readline functions.
